1 The DX200 provides private, secure communication. Each base station can have up to fifteen Beltpacs “registered” to it. Four of the fifteen Beltpacs can transmit at the same time. However, by connecting two or more base stations together, these numbers can be increased. For example, two base stations can support thirty Beltpacs, of which eight can transmit at the same time. Beltpacs can be used either in the push-to-talk or hands-free mode. The base station operator can stop any Beltpac from transmitting. The DX200 can be used with RTS® and Clear-Com® cabled intercom systems. On the intercom channel, 2-wire and 4-wire cabled intercoms can be operated at the same time. Also, using the AUX In and AUX Out connections, a second 4-wire intercom channel can be used. Either a monitor speaker or a local headset can be used with the DX200. Using a local headset, the base station operator can talk to crew members on the cabled intercom channel, Beltpacs only or all channels. The base station can be operated using standard DC electricity or a vehicle electrical system for mobile operation. A power adapter and cable are included with the base station. SECTION 1.

Charge all the Beltpac batteries while the other equipment is being installed. Charging time is about 2.5 hours. Connect AC Adapter • Connect the battery charger cable to the AC adapter as shown to the right. Match the wires labeled AC and GND to the terminals on the adapter with the same labels. • Plug the adapter into an electrical outlet. The red lights on the charger will come on and go off, and then the yellow lights will come on and stay on. Charge Batteries Up to four batteries can be charged in the battery charger at the same time. The battery status lights next to each charging port are explained below. Up to six fully charged batteries can be stored in the battery storage ports. • Insert a battery in each of four charging ports until it clicks in place. • A yellow light next to each charging port stays on while the port is empty. When a battery is in a charging port, a flashing yellow light next to it indicates CHARGE PENDING, which means the battery is too hot. Adjust the room temperature or move the charger to a cooler area. When a battery is in a charging port, a yellow light on steady next to it means CHARGE FAILED. If this happens, follow the instructions on the side of battery charger. • A red CHARGING light next to a battery port stays on while a battery in the port is charging. A green READY light next to a battery port goes on when a battery in the port is fully charged. Store fully charged batteries in storage ports. Batteries should not be left in charge ports after being fully charged. If a battery is left in a charge port for more than three weeks, the yellow indicator may light up. In this case, it does not indicate a faulty battery. SECTION 2.

5 BELTPAC SETUP AND REGISTRATION The first time you operate the DX200 system, you must register each Beltpac for use with a specific base station. The base station will then recognize all registered Beltpacs when their power is on, and will know the difference between them and other electronic equipment operating on the same frequencies. If a Beltpac is added or replaced later, the new one must be registered and the old one remains in memory. A maximum of 15 Beltpacs can be registered to a single base station at one time. Set Up Beltpacs Before registering them, set up all Beltpacs as follows. Step 1. Insert a fully charged battery in the Beltpac, with the metal contacts on the end of the battery inserted first. Press it in until it snaps. Step 2. Place the Beltpac in the pouch. Step 3. Plug the headset cable connector into the Beltpac. Register Beltpacs Beltpacs must be within 6 feet (1.83 meters) of the base station while you are registering them. Be certain the base station power is on, and each Beltpac you are going to register is turned off before you begin. Beltpacs that are already registered can be on or off. Step 1. Put the headset, of the Beltpac being registered, on your head. Step 2. Press the REGISTER BELTPAC button on the front panel of the base station (#7 on base station front panel illustration). • The REGISTRATION STATUS display (#6 on base station front panel illustration) will show a small “o” for open. NOTE: If you wait too long before going on to Step 3, the base station will go out of the registration mode and you will have to repeat Step 2. Step 3. Press and hold the ISO button on the Beltpac while you press and release the PWR (power) button to turn the unit on, then release the ISO button. This will cause the Beltpac to enter the registration mode. • The two power lights at the corners of the Beltpac near the IC and ISO buttons will begin blinking red, then will blink green two or three times and go off. • Wait! There may be a short delay. If registration is successfully completed: • A voice message in the headset will say “Power on, Beltpac #, Version #, Begin registration, Registration complete, …” • After a delay of up to 15 seconds, the REGISTRATION STATUS display will show the ID number assigned to this Beltpac for about 10 seconds. NOTE: ID numbers are assigned sequentially as 0 thru 9, A, b, C, d and E. • The power light on the Beltpac, next to the IC button, will remain on steady green. • Repeat Steps 1 to 3 above for each Beltpac to be registered. Step 1 Step 2 Step 3

6 If registration failed: • A voice message in the headset will say “Power on, Beltpac #, Version #, Begin registration, …” Both power lights on the Beltpac will be blinking red, and there may be a delay of up to 90 seconds before you hear “Registration failed.” • Press the RESET button on the base station. To press the RESET button, insert a small paper clip or similar object into the RESET hole at the lower-left corner of the base station front panel. When the REGISTRATION STATUS display becomes blank, press the REGISTER BELTPAC button and register the Beltpac again. If registration fails again, call your dealer for assistance. If you try to register more than 15 Beltpacs: • An F will appear on the REGISTRATION STATUS display on the base station and you will hear “Registration failed” in the headset. • Clear all current registrations by pressing the RESET REGISTRATION button and the RESET button at the same time. To press the RESET button, insert a small paper clip or similar object into the RESET hole at the lower-left corner of the base station front panel. Continue holding the RESET REGISTRATION button after you release the RESET button, until the clear code “c” (lower case) appears on the REGISTRATION STATUS display. • Register all active Beltpacs, one at a time. Previously registered Beltpacs must be re-registered. NOTICE You have completed the stand-alone system setup. The instructions under INTERCOM AND AUXILIARY EQUIPMENT SETUPS on the following pages are for setting up additional equipment which you may want to use with your DX200, such as a 2-wire intercom, 4-wire intercom, an external speaker or other auxiliary audio equipment.

NOTE: The above settings are saved in memory and only need to be repeated when you want to change between hands-free and PTT operation. When changing modes, if both power lights begin blinking, turn the Beltpac off and begin again. Hands-free and Push-To-Talk mode settings affect both IC and ISO. Individual adjustment is not possible. • Push-To-Talk Mode Operation – press and hold the IC or ISO button for more than one second. In PTT operation, audio will be transmitted only while you are pressing the IC or ISO button. • Hands-free Mode Operation – Quickly press and release the IC or ISO button to “latch” the transmitter on. Talk and listen, as in a normal telephone conversation. Press and release the IC or ISO button again to “unlatch,” to end the conversation. All Beltpacs can be unlatched by the base station operator, by pressing the UNLATCH button on the base station. NOTE: In hands-free mode, pressing the IC button while latched in ISO will latch on IC. Pressing the ISO button while latched in IC will latch on ISO. Volume Up/Down • Volume Up Adjustment – Each time you press and release the volume-up S button, a beep will be heard in the earpiece as the volume increases one step. If you press and hold the volume-up button, repeating beeps will be heard as the volume steps up to maximum. When maximum volume is reached, “maximum” will be heard in the earpiece, and will be repeated until you release the volume-up button. • Volume Down Adjustment – Each time you press and release the volume-down T button, a beep will be heard in the earpiece as the volume decreases one step. If you press and hold the volume-down button, repeating beeps will be heard as the volume steps down to minimum. When minimum volume is reached, rapidly repeating beeps will be heard.

12 Microphone Gain Adjustment Some users talk louder or softer than others. To allow for this, microphone gain adjustment is provided. To increase microphone gain – Press the volume-up S button while holding down the ISO button in the normal operating mode. The microphone gain increase can be monitored through sidetone, or preferably by someone else on a Beltpac or at the base station. To Decrease microphone gain – Press the volume-down T button while holding down the ISO button in the normal operating mode. The microphone gain decrease can be monitored through sidetone, or preferably by someone else on a Beltpac or at the base station. NOTE: You will hear “Maximum” if you attempt to go higher than maximum microphone gain. You will hear beeps if you attempt to go lower than minimum microphone gain. Microphone gain will be saved in non-volatile memory and does not require readjustment each time the power is turned on. Batteries Change Batteries When a battery becomes weak, a voice in the earpiece will say “Change battery.” When this happens, take the Beltpac out of its pouch and remove its battery. Slide the arrow-shaped battery-release latch in the direction of the arrow. Pull up on the end of the battery near the battery-release latch and lift the battery out of the Beltpac, or turn the Beltpac over and catch the battery in your hand.

Press the top of the battery carefully into the battery holder until it snaps in place under the battery-release latch. Battery release latch Battery

13 If you are unable to correct any of the problems described below, contact your dealer for assistance. • Red light on base station power switch does not come on. Be certain power cords are properly connected to base station, power supply and electrical outlet. • Beltpac power lights do not turn green and “out of range” is heard in the headset. Be certain your base station power is on. Turn the Beltpac and base station power on and off. You may be too far from the base station. The range varies with each location’s layout. • When trying to register, it keeps saying registration failed. Clear registration as described on page 7, and repeat the registration procedure. • Others cannot hear me when I talk. Be certain the headset is securely connected to the Beltpac or base station, and that you are pressing the IC or ISO button on the Beltpac, or the TALK button on the base station. Be certain the appropriate IC or ISO setting is selected under LOCAL HEADSET on the base station. • People on the 4-wire intercom cannot hear me or I cannot hear them. Be certain the cables are securely connected and the 4-wire intercom is on. If using a local headset, be certain the IC setting is selected under LOCAL HEADSET on the base station. • People on the RTS/ClearCom systems cannot hear me or I cannot hear them. Be certain the cables are securely connected and the 2-wire intercom is on. If using a local headset, be certain the IC setting is selected under LOCAL HEADSET on the base station. • The 2-wire intercom is on and there is a loud squeal whenever I try to talk. This can occur if two or more base stations are daisy-chained and the JP1 jumper on the circuit board in one of the base stations has not been adjusted as described in Step 12 on page 6. • Settings are not retained when the base station power is turned off and on again. The internal battery may be low. Contact your dealer. SECTION 4. TROUBLESHOOTING In the event of an electrical power outage — such as from a lightning storm or power generator failure, if you experience problems with your HME equipment after the electricity comes on again, unplug the AC power adapters from their electrical outletsand wait 15 seconds, then plug them back in. 2400MHz cordless telephone interference — If there is a 2400MHz cordless telephone nearby, interference may occur. However, because the DX200 is a frequency-hopping system, this problem is unlikely. If it does occur, changing frequencies on the telephone may alleviate the problem. If not, move the phone as far as practical from the base station, or use another type phone.

17 APPENDIX A: BATTERY CHARGER 230 VOLT AC ADAPTER CONNECTIONS If your DX200 will be used outside the U.S.A., where a 230 Volt AC adapter is required for your battery charger, connect the AC adapter to the battery charger as follows. Step 1. Connect an electrical plug to the wires on the power cable according to color codes. (Brown = live, Blue = neutral, Green with yellow stripes = ground) Step 2. Plug the other end of the power cable into the receptacle on the AC adapter. Step 3. Remove the spade lugs from the brown and blue wires of the battery charger cable and cut the green/yellow wire as short as possible. No ground wire will be used. Cut the connector off the AC adapter output cable. Strip enough of the insulation from the wires of both cables so they can be spliced. Splice the wires from the AC adapter cable to the “AC” wires of the battery charger cable. Cover the splice with electrical tape or shrink tubing. Step 4. Plug the electrical plug into an AC electrical outlet.
