2. Press the CLR button to monitor the channel. Noise will be heard if there is no activity on the channel. This function is also useful for setting the desired volume level. 3. You will hear the voice message automatically if a valid message is received by your radio. SENDING A MESSAGE 1. Make sure the radio is turned ON, and the proper Channel and System have been selected. 2. Press and hold the CLR switch and then adjust the VOLUME controls for the desired listening level. Release CLR switch. 3. Decide what you want to say. If you intend a lengthy message (or several messages), the vehicle engine should be running to maintain the battery charge. 4. Observe the BSY indicator and then press CLR the switch to assure that the channel is not in use. 5. Remove microphone from the hanger, press the PTT switch and TXidentify yourself. The indicator will be shown each time the PTT switch is pressed. 6. Release the PTT switch and wait for an answer to your call. Then complete your message. 7. When the PTT switch is pressed continuously for a pre-programmed time (default of 30 seconds), the carrier control timer (if enabled) will sound a pulsed alert tone and unkey the transmitter. Release and press the PTT switch again to reset the timer and resume conversation. NOTE Always speak in a normal tone of voice. Hold the microphone cupped in your hand and touching your cheek lightly. Speak across the face of your microphone, not directly into it. Shouting will degrade your transmission, so do not speak any louder than normal. SCAN OPERATION SCAN SETUP You may program your radio to scan a number of Channels for activity on the selected system. Starting Or Stopping SCAN Press the SCAN button to alternate between Scan on (SCN indicator illuminated) and Scan off (indicator dark). Adding/Deleting To/From SCAN SCAN should be off before changing the SCAN list. 1. Press the menu button until SCAN A/D is displayed. 2. Press the CHANNEL/SEL (-) button until the CHANNEL name is displayed. 3. Press the CHANNEL/SEL (+) button until the desired priority level is displayed by the scan priority indicators on the right side of the display; the choices are S, P2; P1 or all off (all off removes the channel from the SCAN list). 4. Press the CLR button when completed to return to normal operation. If your radio has one of the auxiliary keys preprogrammed to edit the SCAN list, the list may be changed by using the CHANNEL/SEL buttons to display the CHANNEL name, and then pressing the auxiliary key until the desired level is displayed. NOTES 1. The radio will remember the scan state through a power cycle unless programmed with a predefined power up state. 2. The radio may be programmed to stop scanning when the microphone is removed from the hookswitch. 3. When the radio is programmed, a FIXED SCAN list can be specified. If this is done, the SCAN list cannot be changed. 4. A previous channel with priority will become a non-priority scan channel when a new priority channel is programmed. The SCAN function allows monitoring of up to 16 receive channels on the selected system. The scanned channels may be any frequency within the frequency band limits of the radio and may be Channel Guard protected. All scan functions are retained in memory, even if the 12 Volt vehicle battery is disconnected. Any channel may be scanned with or without a priority level. One channel may be programmed for Priority 1 (P1) and another for Priority 2 (P2) with any or all remaining channels programmed as non-priorities. RECEIVER SCAN RATE The scan rate for the radio will vary depending upon the number of channels programmed into the scan list and whether or not Channel Guard is programmed. The scan rate will be faster when fewer channels are programmed into scan memory. Scan operation will be determined by the following conditions: • PRIORITY 1, PRIORITY 2 and NON-PRIORITY PROGRAMMED The Priority 1, Priority 2 and up to 14 remaining channels will be scanned. Once a carrier is detected (and if programmed, the correct Channel Guard is decoded), the display will indicate that channel. Sampling of the Priority 1 and Priority 2 channels continues while receiving a message. Should a Priority 1 or 2 channel carrier (and correct Channel Guard) be detected while a non-priority channel is being received, the applicable indicator, P1 or P2 lights, and the channel is switched to the Priority 1 or 2 channel regardless of what is being received on the non-priority channel. • NON-PRIORITY PROGRAMMED Up to 16 non-priority channels may be scanned. Once a carrier is detected (or correct Channel Guard is decoded) the digital display will indicate that channel. Scanning will stop and remain on the channel until the carrier disappears; after a few seconds scanning resumes. The channels are scanned in descending order.
