Important safety instructions When using CeoTronics products do not fail to comply with the following safety information: z Before using CeoTronics products read completely the appropriate operating instructions. If in doubt, ask our technical staff. z If repair work of any kind needs to be done to CeoTronics products, arrange for it to be performed only by the company CeoTronics or by a specialized workshop that is authorized by CeoTronics. In all other cases our warranty and liability for the product shall lapse. z If products are operated on a mains voltage, always pull the mains plug out of the mains plug socket before opening such products (e.g. for servicing purposes) ! z Do not store CeoTronics products outside or in damp ambient conditions. At all times keep them clean, dry and at normal air humidity. CeoTronics products must not be stored in areas with a temperature of over +80° C (+176° F), e.g. in the summertime on the parcel shelf of a car. If not stated otherwise, the following temperature ranges are allowed for CeoTronics products: -10 to +55° C (+14 to +131° F) for operation, -40 to +80° C (-40 to +176° F) for storage. z Do not immerse a CeoTronics product into water, if it is not expressly specified for this purpose. z When using CeoTronics products that are equipped with connection leads ensure that the latter do not get caught up in operational machinery or wheels ! z Type-tested muffs with a high degree of passive noise attenuation are used for CeoTronics headsets with headset muffs. If not stated otherwise, it is our experience that the passive noise attenuation of the headset muffs is reduced by approx. 3 dB due to the electronics that are integrated into the headset muffs. As a rule no empirical values are available for non-standard products. At very high noise levels that exceed the passive protective effect of the headset muffs we recommend that ear plugs be worn as an additional measure. If in doubt, ask your safety officer or company doctor. Full noise attenuation exists only if the muff padding is in perfect condition. This should be replaced at the latest after every 6 months of use. z In the case of headsets with headset muffs that protect against harmful ambient noise and that are not equipped with additional electronics for level-limited ambient sound reception, take heed that the audibility of warning signals, warning calls etc. is also impaired ! z CeoTronics products that are not intrinsically safe (explosion-proof) and therefore have no special explosion-proof designation must never be operated in potentially explosive environments (e.g. when refuelling cars, aircraft etc.). Devices that are not explosion-proof can unintentionally trigger off explosions in such areas ! z Connect CeoTronics accessories to a device or disconnect them from a device only when the device is switched off. z If you are a cardiac pacemaker carrier, before operating a transmitter/receiver ask the manufacturer of your cardiac pacemaker for information about any impairment that might be caused due to high frequencies. z For safety reasons reception volumes in excess of 85 dB(A) are possible with a whole series of CeoTronics products. However, these can be regulated by the user. After switching on the communication system, set the reception volume to approx. 1/2 the available loudness volume and then test the audible volume. Do not set the volume any higher than is necessary. A very high volume setting can lead to damaged hearing, particularly if it is continuous. For high volumes or noise levels wear additional ear plugs. If in doubt, ask your safety officer or company doctor. z When on board an airplane always keep a transmitter/receiver switched off. Operation of the transmitter/receiver could affect the safety of the airplane and it is therefore prohibited. Never operate electronic devices on board an airplane without the express approval of an authorized member of the cabin crew. z Do not leave CeoTronics products lying around loose in cars, e.g. on the parcel shelf. Stow these products in a suitable, safe place in the car so that they do not present a danger to you or to other occupants of the car, if emergency braking is effected. z When driving a car, do not use the radio because it may distract you from the other traffic. Never use a CeoTronics product (headset, insert earphone, induction receiver etc.) that will impair your hearing. z Charge rechargeable batteries only with the appropriate suitable CeoTronics charger. Observe the voltage and currency specifications, including those on the mains face (e.g. 230 V AC or 115 V AC). Never use the charger to recharge non-rechargeable batteries. z When handling rechargeable batteries comply with environmental protection regulations ! Rechargeable batteries contain toxic chemicals (e.g. cadmium). Never attempt to open a rechargeable battery and never throw a rechargeable battery into fire. Expended (defective) rechargeable batteries are subject to compulsory regulated waste disposal. Do not put them in the household waste ! z Ensure that a short-circuit (risk of fire or injury) is not created across rechargeable battery terminals or charging sockets by a short-out (bent-open paper clip, bunch of keys etc.). In such an event the warranty shall lapse. Transport any spare rechargeable batteries in an electrically non-conducting package in order to avoid short-circuiting the rechargeable batteries. z Keep CeoTronics products and rechargeable batteries out of the reach of children and any other persons who are not familiar with the handling and operation thereof. z Packaging materials, e.g. filling materials and plastic bags are not toys and have to be kept out of the reach of children. There is a risk of children ingesting them and choking ! z Safe operation requires clean devices. Ensure that the devices (microphones, connectors etc.) are clean and in good condition at all times. z CeoTronics products may only be used for the specific application envisaged. z If the device is to be put out of operation definitively, bring it to a local recycling plant for disposal or send it to CeoTronics. Important Note Please note that any changes or modifications not expressly approved by the party responsible for compliance will void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Declaration concerning RF Radiation Exposure: The CT-DECT.24/CT-GateCom II.24 system is considered to be a portable transceiver. A portable device is defined to be used so that the radiating structure of the device is within 20 centimeters (7.9 in.) of the body of the user and no specific safety distance is needed. Fig. 1 System overview 2. Description 2.1 General This duplex communication system (Fig. 1) is used for aircraft push-back. The tug driver, two wing walkers and marshalling agent wear headsets in conjunction with Transmitter/Receiver Units »CTGateCom II.24/Multi«. The four headset wearers outside the aircraft can communicate with one another. The tug driver is able to communicate with the flight deck via the Aircraft Interface that is connected to the aircraft intercom on the outside of the aircraft. Detailed information see section 2.2. The range depends on the local circumstances. Protection against eavesdropping is ensured by the digital design. Channel selection is effected automatically. 2.2 Communication circuits Wing walkers The two wing walkers can communicate with each other, with the marshalling agent, and with the tug driver. The wing walkers are not able to speak to the flight deck. But they are able to hear the communication between the flight deck and the tug driver. Marshalling agent The marshalling agent can communicate with the two wing walkers and with the tug driver. He is able to hear the communication between the flight deck and the tug driver. When the tug driver speaks to the flight deck the marshalling agent can also speak to the flight deck as long as the microphone switch at the left headset muff of the tug driver is in position »PTT« or »HOT«. Tug driver The tug driver can communicate with the two wing walkers, with the marshalling agent, and with the flight deck. When he communicates with the wing walkers and/or with the marshalling agent the flight deck doesn‘t hear this communication. When the tug driver communicates with the flight deck the two wing walkers and the marshalling agent will hear this communication also. The tug driver is the only person who is able to control the communication with the flight deck. Flight deck The flight deck can only communicate with the tug driver. The two wing walkers and the marshalling agent can hear this communication as well. When the tug driver speaks to the flight deck the marshalling agent can also speak to the flight deck as long as the microphone switch at the left headset muff of the tug driver is in position »PTT« or »HOT«. 2.3 System overview The system (Fig. 1) consists of: y four GroundCom Headsets y four Transmitter/Receiver Units CT-GateCom II.24/Multi y one Aircraft Interface CT-GateCom II.24+4 y one charging station for up to four removable Li-Ion rechargeable battery packs 3.6 V/2300 mAh y one single-unit charger for the Li-Ion rechargeable battery 3.6 V/2300 mAh in the Battery Pack of the Aircraft Interface CT-GateCom II.24+4 2.4 Communication Headsets 2.4.1 General The wing walkers, the marshalling agent and the tug driver use GroundCom Headsets in conjunction with Transmitter/Receiver Units CT-GateCom II.24/Multi. The GroundCom Headsets protect against harmful ambient noise and allow communication in noisy environments. The headset microphone is noise-compensating and is equipped with a flexible gooseneck and windshield. The microphone can be switched on and off by means of a switch at the headset muff. 2.4.2 Headset, basic version Fig. 2 Headset, basic version Key to Fig. 2 a Adjustable head band b Ear cushions c Left headset muff d Microphone and windshield e Flexible gooseneck Option – External PTT button with belt clip for communication between the wing walkers, the marshalling agent, and the tug driver g Connecting cable and plug for the Transmitter/Receiver Unit CT-GateCom II.24/Multi h Right headset muff On/Off switch for microphone The 3-position microphone switch at the right headset muff allows communication between the wing walkers, the marshalling agent, and the tug driver but not with the flight deck.

Information for the microphone switch see section 2.4.6 2.4.4 Headset with level-limited ambient sound reception Fig. 4 Headset with level-limited ambient sound reception General – Headsets with level-limited ambient sound reception (Fig. 4) are used mainly where ambient sounds, warning signals etc. have to be heard alongside communication. The external sounds are received by a microphone (Fig. 4/b) on the front side of the left-hand headset muff and are audible inside this headset muff via the ambient sound speaker. If the external sounds exceed 85 dB(A), the sound level emitted to the ear by the ambient sound speaker is limited electronically to a maximum of 85 dB(A). The power for the ambient sound reception electronics is supplied by the Transmitter/Receiver Unit CTGateCom II.24/Multi. Switching On/Off and adjusting the volume for ambient sound reception – The ambient sound reception is switched on and off and volume controlled by means of the additional combined On/Off switch and volume adjuster (Fig. 4/a) on the headset muff. 2.4.5 Audio signals used Two different audible tones are used for signaling the operating status via the headset connected to the Transmitter/Receiver Unit. The tone for the indication of positive responses (P-tone) has a higher frequency than the tone for the indication of negative responses (N-tone). Signaling of the various events is effected by a varying number of consecutive P-tones or N-tones. Positive acknowledgement tone All positive responses are indicated by a high P-tone. Negative acknowledgement tone and error tone All negative responses and error status are indicated by a low N-tone. Examples battery warning If the battery has an undervoltage a low 3-beep N-tone sequence »N-N-N« sounds approximately every 10 seconds in the Headset. Examples range warning If the range limit is reached, a high 3-beep P-tone sequence »P-P-P« sounds approx. every 5 seconds in the Headset. 2.4.6 On/Off switch for the microphone The microphone of the headset can be switched on and off with the microphone switch »PTT.–OFF– HOT.« at the bottom of the headset muff(s). Three switch positions are possible. However, communication can only be performed after on-air subscription (sections 3...3.4) that is carried out exworks, switching on, synchronization, adjustment of the speaker volume (sections 4...4.3) and connection setup (sections 4.4...4.4.2) have all been effected. Middle position »OFF« (receive): The headset microphone is switched off. You can only receive. Front switch position »PTT« (transmit and receive): »PTT« position (PTT = push-to-talk). The headset microphone is switched on. You can speak into the microphone as long as you hold the switch in this position and simultaneously a message is being received. After releasing the switch, the switch returns to the middle position »OFF«. Rear »fixed« switch position »HOT« (transmit and receive): »Hot mic« position. The headset microphone is constantly switched on. You can speak into the microphone and simultaneously receive a message. 2.4.7 Wearing the headset with an additional head strap In the event of rapid body movements or extreme body postures or if you are using a protective helmet the headset can be additionally secured on your head by means of the head strap (Fig. 5/a) provided. a. Pull the head strap as per Fig. 5 through the slit in the headset muffs and fasten it with the two retainers (Fig. 5/b). b. Put on the headset, fold the head band (Fig. 5/c) to the rear and wear the head band as a neck band. Ensure that the head strap and neck band are tautly seated. Fig. 5 2.5 Transmitter/Receiver Unit CT-GateCom II.24/Multi Fig. 6 Transmitter/Receiver Unit CT-GateCom II.24/Multi The wing walkers, the marshalling agent and the tug driver have Transmitter/Receiver Units CT-GateCom II.24/Multi which are used in conjunction with the headsets. They are worn on waist belt by means of a fastening clip on the rear. The Transmitter/Receiver Unit is used for communication over short distances. The max. range depends on the local circumstances. Protection against eavesdropping is ensured by the digital design. Channel selection is effected automatically by the unit.

On-air subscription 3.1 General Î NOTES z The on-air subscription is a procedure which has to be performed once only ex-works. It must be performed again only in the case of an error or if another Transmitter/Receiver Unit CT-GateCom II.24 will be used in conjunction with the Aircraft Interface. z In the following the on-air subscription is described for the Aircraft Interface in conjunction with Transmitter/Receiver Units CT-GateCom II.24/Multi. The on-air subscription for the Aircraft Interface in conjunction with Transmitter/Receiver Headsets CT-GateCom II.24 is carried out analogous and in the sequence as described in sections 3.2...3.4. The subscription procedure is performed on the Aircraft Interface and the Transmitter/Receiver Units manually by means of a procedure carried out by the operator. The Aircraft Interface is equipped with two radio modules. The four Transmitter/Receiver Units are equipped with one radio module each. Each unit (radio module) has its own identification number. A max. of four Transmitter/Receiver Units (in two groups) is allocated to the two radio modules in the Aircraft Interface. The Aircraft Interface is the base unit and the Transmitter/Receiver Units are subscribed to the Aircraft Interface. First of all an allocation must always take place between the Aircraft Interface and the Transmitter/Receiver Units. Ex-works the four Transmitter/Receiver Units are divided in two groups as follows (Fig. 10/i and h): y Group 1 – Transmitter/Receiver Units with red colored push-button bank for tug driver and marshalling agent. The subscription is carried out by means of the red subscription button »T« (Fig. 10/i) for group 1 at the Aircraft Interface y Group 2 – Transmitter/Receiver Units with black colored push-button bank for wing walkers. The subscription is carried out by means of the black subscription button »W« (Fig. 10/h) for group 2 at the Aircraft Interface Other allocations in pairs can be carried out later by the customer. Please heed that the subscription of the Transmitter/Receiver Units in conjunction with the Aircraft Interface is always carried out in pairs. If a third Transmitter/Receiver Unit is subscribed to one of the two groups of the Aircraft Interface, the Transmitter/Receiver Unit that was subscribed first is deleted from the data base of the Aircraft Interface. Once the subscription procedure has been successfully concluded, the identity of the communication partners is stored in the data base of the Aircraft Interface and of the Transmitter/Receiver Units. A Transmitter/Receiver Unit stores one Aircraft Interface, the Aircraft Interface stores in pairs up to four (2 x 2) Transmitter/Receiver Units. If the Aircraft Interface or a Transmitter/Receiver Unit is set to subscription mode and this is terminated or not completed after 2 minutes without the subscription procedure having been successfully concluded a »time out« occurs. After a »time out« the subscription procedure must be restarted. 12 3.2 On-air subscription of the first Transmitter/Receiver Unit of group 1 Î NOTE z The Transmitter/Receiver Units are subscribed in pairs (group 1 and 2 see section 1), but one after the other, to the Aircraft Interface. First the two Transmitter/Receiver Units of group 1 are subscribed one after the other to the Aircraft Interface and then the two Transmitter/Receiver Units of group 2 are subscribed one after the other to the Aircraft Interface (see section 3.1). z Two Transmitter/Receiver Units can never be simultaneously subscribed to the Aircraft Interface. The Transmitter/Receiver Units must always be subscribed one after the other to complete a group. z For subscription the Aircraft Interface must always be switched on before the Transmitter/Receiver Unit. a. Connect the first headset of group 1 to the first Transmitter/Receiver Unit of group 1 (identifiable by the red colored push-button bank) via the connecting cable and plug of the headset. Open the carrying bag for the Aircraft Interface by means of the zip. b. At the Aircraft Interface press the red subscription push-button »T« (Fig. 10/i) for group 1, keep the red push-button »T« pressed and switch on the Aircraft Interface by means of the green push-button ON (Fig. 10/e). The control lamp (Fig. 10/f) illuminates. After switching on keep the red subscription push-button »T« pressed for at least 10 seconds. Than immediately carry out step »c«. c. At the first Transmitter/Receiver Unit group 1 with red colored push-button bank press the subscription button 1 simultaneous with subscription button 5 located at the begin and end of the push-button bank (Fig. 6/c). Keep the two push-buttons pressed and switch on the Transmitter/Receiver Unit by means of the On/Off switch and volume control (rotary knob Fig. 6/b). After switching on keep the two push-buttons pressed for at least 10 seconds. The subscription procedure on the Transmitter/Receiver Unit has to be started within 2 minutes after the subscription procedure on the Aircraft Interface was started, otherwise a »Time Out« may occur (see section 3.1). After approx. 30 seconds a high double-beep tone can be heard in the headset. This indicates that the on-air subscription has been successfully completed. A second high double-beep tone finally reports that the Transmitter/Receiver Unit has synchronized itself with the Aircraft Interface. 3.3 On-air subscription of the second Transmitter/Receiver Unit of group 1 a. Switch off the Aircraft Interface with the red push-button OFF (Fig. 10/g). The control lamp (Fig. 10/f) extinguishes. b. Connect the second headset of group 1 to the second Transmitter/Receiver Unit of group 1 (identifiable by the red colored push-button bank) by means of the connecting cable and plug of the headset. Ensure that the Transmitter/Receiver Unit is switched off. The on/off switch and volume control (rotary knob Fig. 6/b) must be set to OFF . c. Repeat the subscription procedure for the Aircraft Interface and the second Transmitter/Receiver Unit of group 1 as described in section 3.2, steps »b« and »c«, for the Aircraft Interface and for the first Transmitter/Receiver Unit of group 1. 3.4 On-air subscription of the first and second Transmitter/Receiver Unit of group 2 The subscription procedure for the Aircraft Interface and the two Transmitter/receiver Units of group 2 (identifiable by the black colored push-button bank) is carried out as described in sections 3.2 and 3.3 for the two Transmitter/Receiver Units of group 1. At the Aircraft Interface the black subscription pushbutton »W« (Fig. 10/h) for group 2 is used instead of the red push-button »T« for group 1 (Fig. 10/i). 13 4. Commissioning and operation Î NOTE In the following the commissioning and operation of the system is described for the Aircraft Interface and the Transmitter/Receiver Units CT-GateCom II.24/Multi which are used in conjunction with communication headsets. 4.1 Aircaft Interface The rechargeable battery in the Battery Pack must be fully charged. a. Open the carrying bag for the Aircraft Interface by means of the zip. b. Take the connecting cable (Fig. 11/a) with male jack-plug (Fig. 11/c) out of the cover of the carrying bag. Lead the connecting cable with male jack-plug through one of the loops (Fig. 11/b) on the carrying bag. Close the carrying bag by means of the zip. This prevents any fluids running along the lead into the carrying bag. Fig. 11 c. At the aircraft locate the aircraft intercom connector. Hang the carrying bag e.g. over the access cover or to a suitable place near the aircraft intercom connector by means of the carrying strap or by means of a hook. Connect the Aircraft Interface via the connection cable and the male jack-plug to the female jackplug for the aircraft intercom. Î NOTE z Keep the carrying bag for the Aircraft Interface closed at all times while in use! 4.2 Headsets and Transmitter/Receiver Units a. Connect the headset via the connecting cable and plug to its Transmitter/Receiver Unit. Fasten the Transmitter/Receiver Unit by means of the clip on the rear to a suitable place on your clothing. b. Put on the headset. Take care for a perfect comfortable fit. Only when the ear cushions are properly located around the ears the best noise attenuation of the ear muffs is provided. Adjust the height of each ear muff equally on both sides while holding the head band down until the ear cushions have a tight and comfortable fit. The head band should sit straight and comfortable on the top of the head. For hygiene reasons we recommend the use of the washable sweat absorbers on the ear muffs. These are pulled over the ear cushions and are for the purpose of wear comfort and hygiene. 14 CAUTION Do not »twist« the flexible gooseneck. Do not carry the headset by the gooseneck. Use the microphone only with a windshield. c. Adjust the flexible gooseneck by bending so that the microphone is located at a distance of approx. 5 mm (0.2 in.) in front your lips. Optimum voice transmission with the best possible noise compensation is then provided. 4.3 Switching on, adjusting the speaker volume Î NOTES z The Aircraft Interface must always be switched on before the Transmitter/Receiver Units. z On the Transmitter/Receiver Units the push-buttons 2,3,4 for connection setup and connection release, placed in the middle of the push-button bank (Fig. 6/c), must not be pressed until the Transmitter/Receiver Units are synchronized with the Aircraft Interface. z Always leave the Aircraft Interface and the Transmitter/Receiver Units switched on as long as you work with the communication system so that immediate availability of the system is provided. a. First switch on the Aircraft Interface by means of the green push-button ON (Fig. 10/e). The control lamp (Fig. 10/f) illuminates. If the Battery Pack voltage is too low the control lamp flashes and the Battery Pack must be charged. b. Switch on the Transmitter/Receiver Unit by means of the On/Off switch and volume control (rotary knob Fig. 6/b). After Switching on the connection synchronization between Transmitter/Receiver Unit and Aircraft Interface is effected automatically. Synchronization: A click is audible in the headset connected to the Transmitter/Receiver Unit approximately 10 seconds after switching on. The synchronization procedure then begins, i.e. the previously switched on Aircraft Interface seeks its Transmitter/Receiver Unit. This synchronization procedure can last approx. 30 seconds. Upon completion of synchronization – i.e. the Aircraft Interface has found its Transmitter/Receiver Unit – a high double-beep P-tone sounds in the headset, indicating that the Transmitter/Receiver Unit and the Aircraft Interface are ready for operation. c.
