To start/stop scan: Push the [SCAN] switch. · Scan pauses on a channel when receiving a signal. [. . . ] (Optional UT-105 SmarTrunk IITM Logic Board is required. ) The optional UT-105 allows communication over conventional channels or SmarTrunk IITM channels. Push the [Bank Up] switch one or more times. · Scanning starts when a channel bank for SmarTrunk IITM is selected. (See p. 9 for more detailed operation. ) D HIGH/LOW POWER OUTPUT This function selects high or low power for a channel. To toggle between high and low power: Push the [HIGH/LOW] switch. · "LOW" appears when low output power is selected. D EMERGENCY FUNCTION The emergency function allows you to send your ID quickly and easily to your Base Station, etc. To activate the emergency function: Push and hold the [EMERGENCY] switch for 1 sec. · The transceiver selects a pre-programmed channel, then sends an emergency signal to your Base Station. · The pre-programmed channel remains selected until a control signal is received from the Base Station or power is turned OFF. 6 CONVENTIONAL OPERATION I Receiving and transmitting NOTE: Transmitting without an antenna may damage the transceiver. w Listen for a transmission and adjust [VOL] to a comfortable listening level. · When no transmission is heard, push and hold monitor while adjusting [VOL] (your transceiver may not be programmed with the monitor function). 4 I Call procedure When your system employs tone signalling (excluding CTCSS and DTCS), the call procedure may be necessary prior to voice transmission. The tone signalling employed may be a selective calling system which allows you to call specific station(s) only and prevent unwanted stations from contacting you. q Select the desired Tx code channel or 5-tone code according to your System Operator's instructions. · This may not be necessary depending on programming. · Refer to the next page for selection. The transceiver is now set to receive desired calls on the selected channel. 2) · This sponge is not used when options are installed. 6 q (Fig. 2) 11 7 BATTERY PACKS I Battery cautions NEVER incinerate used battery packs. If the battery pack becomes wet, be sure to wipe it dry BEFORE attaching it to the transceiver. Also, current may flow into nearby metal objects so be careful when placing battery packs in handbags, etc. If your battery pack seems to have no capacity even after being charged, completely discharge it by leaving the power ON overnight. If the battery pack still does not retain a charge (or very little), a new battery pack must be purchased. I Battery pack replacement Before replacing the battery pack, the volume control MUST be rotated fully counterclockwise, until a click is heard, to turn the power OFF. · TO REMOVE the battery pack from the transceiver: Push and hold the battery release downwards, then pull the battery pack upwards with the transceiver facing you. · TO ATTACH the battery pack to the transceiver: Mate the notched ends of the battery pack and the transceiver, and push the battery pack until it clicks into place. D Recycling information (U. S. A. only) The product that you have purchased contains a rechargeable battery. At the end of its life, under various state and local Ni-Cd laws, it may be illegal to dispose of this battery into the municipal waste stream. Call 1-800-8-BATTERY for battery recycling options in your area or contact your dealer. RB RC 12 BRC BATTERY PACKS 7 I Battery case When using a BP-194 OPTIONAL BATTERY CASE attached to the transceiver, install 8 AA (R6) size alkaline or Ni-Cd batteries as illustrated below. D Battery case cautions When installing Ni-Cd batteries: · Make sure all Ni-Cd cells are the same brand, type and capacity. [. . . ] Charge the battery pack before first operating the transceiver or when the battery pack becomes exhausted. If you want to charge the battery pack more than 300 times, the following points should be observed: 1. Use the battery until it becomes almost completely exhausted under normal conditions. We recommend battery charging after transmitting becomes impossible. CP-12L (optional) To [CHARGE] white OPC-254L black (optional) To a 12 to 16 V DC power source D Battery pack life When the operating period becomes extremely short even after charging the battery pack fully, a new battery pack is needed.
