preparation You can operate your transceiver from any of the following sources: Rechargeable power pack (supplied with charger) Six alkaline AA batteries (using the supplied alkaline pack) Vehicle battery power (using optional adapter) OPERATING FROM THE RECHARGEABLE POWER PACK You can use the supplied rechargeable power pack to power your transceiver. This power pack provides 7.2 volts and can operate your transceiver at 2.5 watts(typical power) with the low power button out.
NOTES: Nickel-cadmium batteries deliver more power if you occasionally let them completely discharge. To do this, use the transceiver until BATT appears on the display when you push the PTT. Then fully charge the batteries. If you do not occasionally do this, the batteries temporarily lose the ability to deliver full power. Also, to ensure a full charge, be sure the batteries are at room temperature (above 65 degrees F) when you charge them. Cold batteries do not fully charge.
3. Press the battery holder into the battery holder case. When power is low, BATT appears when you press PTT. Be sure to use six fresh AA alkaline batteries. Never mix different types of batteries, and never mix old and new batteries. OPERATING FROM VEHICLE BATTERY POWER You can operate the transceiver from vehicle battery using a DC power cord (Radio Shack Cat. No. 270-1533). This cord supplies a 13.
Follow these steps to power the transceiver from the 1-amp, 12 volt DC adapter. 1. Connect the barrel plug with the tip set to positive. 2. Insert the adapter's barrel plug into the transceiver's EXT DC jack. CAUTION: Never insert the adapter's barrel plug into the rechargeable power pack's CHARGE jack. Doing so can damage the power pack and transceiver. 3. Plug the adapter into an AC outlet. Follow these steps to power the transceiver from the regulated 2.5 amp power supply.
4. Melt a small amount of solder onto the other end of the wire. Then, connect the red lead to the power supply's + terminal and connect the black lead to the power supply's - terminal. 5. Plug in the power supply and turn it on. Use the meter to confirm you have correctly wired the power connector so that the tip is + and the case is -. 6. Turn off the power supply and plug the connector into the transceiver EXT DC jack.
