For further details, refer to par. 8.4. Rev. 2.0 on 1 March 2004 Page 12 of 32 HM35 Series – User’s Manual 6 BASIC OPERATIONS IMPORTANT! One or more functions among those described from this point onwards can be rendered inactive by your radio network administrator, and depending on the radio’s programming. For this reason, you may find you are not able to access one or more of the functions, or that some functions may differ from the below descriptions. Furthermore, it is possible that one or more functions can be activated via the function keys F1, F2, F3 or F4/ESC, rather than via the normal command menu. In this situation, you will see the (abbreviated) function written directly above the button to which the function has been assigned (in other words, on the bottom part of the display). For further details or when in doubt, contact your vendor/radio network administrator. For information regarding the use of menu commands and function keys, refer to Chapt. 7. 6.1 Turning HM35 on/off To turn on the radio, turn the On/Off-Volume knob clockwise until you hear a click. A welcome message, including the version of software currently installed, will appear on the display. The radio will automatically carry out a self-test, and will emit a beep to confirm start-up. To turn off the radio, turn the On/Off-Volume knob counter-clockwise until you hear a click and the display turns off. 6.2 Volume adjustment To increase volume, turn the On/Off-Volume knob clockwise. To decrease volume, turn the knob counter-clockwise. 6.3 Channel selection To select a channel, press the 6.4 button to scroll through channels upwards or to scroll downwards. Reception There are three reception modes: • Open traffic – this mode allows the user to listen to all communication transmitted on the selected channel and volume. • CTCSS/DCS - if programmed, allows the user to listen only to communication coming from other members of the network with the same CTCSS/DCS tone/code. For further details, refer to Chapt. 9. • Selective call - allows the user to send and receive calls from a user or group. When you receive a valid selective call, the status LED will flash orange and an audio signal will alert you to the incoming call. For further details, refer to Chapt. 9. CTCSS/DCS and Selective Call may be combined together. CTCSS/DCS and Selective call allow for sharing of the same frequency on multiple radio networks. 6.5 Squelch adjustment Your transceiver is equipped with a device able to suppress background noise when no signal is being picked up. You can regulate the threshold of device activation. 1) Press the menu/↵ button to access the command menu, then use the 2) Press the menu/↵ button once more to view the available sub-menus, then of squelch levels) is highlighted.

This indicates that the monitor function is active. 4) Exit the sub-menu by pressing the F4/ESC button, then press it a second time to exit the main menu and return to the standby screen. 6.6.b Monitor using the microphone If the monitor function has been activated (hang-up), you will activate it each time you remove the microphone from its mount. 6.7 Transmission 1) Remove the microphone from its mount. 2) Ensure the channel is unoccupied (otherwise you will create interference), and verify the status LED is off or flashing orange. 3) Hold down the push to talk (PTT) button on the hand-held microphone. The status LED [8] to the right of the display will light up in red to confirm that you are transmitting. 4) Speak in a normal voice approximately 5 – 10cm from the microphone. 5) Release the PTT at the end of the call, ensuring the status LED is no longer lit. 6) At the end of the conversation, hang the microphone back up on its mount. Begin speaking only after having pressed the PTT button and do not release it until you have finished speaking, otherwise all or part of your message will not be transmitted. Do not yell! This does not increase the distance of transmission; rather, your words come across as distorted. Normally, a transceiver will not allow you to send and receive simultaneously, so when you are speaking, others will not be able to do so. Send your message within a reasonable time period so as not to occupy the channel for very long. Consult the following paragraphs for information on correct transmission. 6.7.a Time Out Timer (TOT) The radio can be programmed with an internal TOT (Time Out Timer), which automatically forces your radio into reception mode if you have been speaking for too long (time for this is determined in the programming phase).

Rev. 2.0 on 1 March 2004 Page 21 of 32 HM35 Series – User’s Manual 9 USE WITH CTCSS/DCS AND/OR SELECTIVE CALLS 9.1 Reception In this operating mode, your radio is programmed so that the audio is activated only when receiving a correct CTCSS/DCS and/or selective call signal. The audio will thus remain silent until you receive a correct CTCSS tone, a correct DCS code, and/or a valid selective call. • If a correct CTCSS/DCS signal is received, the status LED will light up in orange for the duration of signal reception, and the icon will appear on the display. • If a valid selective calling signal is received, the status LED will flash orange and the icon will appear on the display. If a signal is received but does not contain the correct tone/code, the audio will remain deactivated and the LED will appear green. Depending on the radio’s programming, it may be possible to temporarily deactivate CTCSS/DCS and Selective call to monitor radio traffic (monitor function). For further details, refer to par. 6.6. 9.2 9.2.a Transmission CTCSS/DCS Transmission If your transceiver has been programmed to transmit a CTCSS tone or a DCS code, you don’t have to do anything. The CTCSS tone or DCS code are automatically sent each time you transmit (the device will not show this status). 9.2.b Sending a selective call Depending on the programming, your transceiver may be able to send up to four selective calls: Call 1 – first selective call (fixed) Call 2 – second selective call (fixed) User – variable selective call; the variable digits can be keyed into the MK06/35-K keypad microphone (refer to. par. 4.1.b). Emergency – selective call for emergencies (special call sent repeatedly, and defined during the programming phase). Rapid send of selective calls Your transceiver can be programmed to send certain selective calls using one or more of the F1, F2, F3 and F4/ESC function keys or using the command menu. Also, the Emergency selective call can be activated via a suitable contact on the rear Input/Output socket. For further details, refer to Chapt. 13. To emit a fixed selective call using the function keys: 1) Ensure the channel is unoccupied by checking that the status LED is off (or flashing orange). 2) Press the F1, F2, F3 or F4/ESC key that corresponds to the call you wish to send. The call will be sent automatically, the status LED will be lit in red, and the display will simultaneously show the selective address corresponding to the button pressed. When you follow the operation outlined in step 2, the device will automatically go into transmission mode (status LED lit in red); therefore, you do not need to press the PTT transmission button on the hand-held microphone.
