NOTE
Lithium Battery Pre-Conditioning
When using BA-5590/U lithium batteries, General Dynamics – C4
Systems recommends that the user consult MIL-B-49430 (ER),
'MIL-SPEC, Batteries, non-rechargeable, Lithium Sulfur Dioxide',
and MIL-B-49430/3D (ER) 'MIL-SPEC, Batteries, non-
rechargeable, Lithium Sulfur Dioxide BA-5590/U.' Particular
attention should be paid to the paragraphs relating to voltage
delay of the BA-5590/U.
It is recommended that the batteries be changed in pairs.
New, unconditioned, lithium batteries may not be able to deliver
the current required to allow the transceiver to transmit in high
power. To condition the lithium batteries the user can, after
installing the new batteries, set the transceiver to low power and
key the transmitter for 20 to 30 seconds, then set the transceiver
to medium power and again key the transmitter for 20 to 30
seconds, the batteries should now be conditioned and capable of
supplying sufficient current to allow the transceiver to transmit in
the high power mode.
The battery case holds two batteries. Always use two of the same type battery when
replacing batteries. To replace the batteries, follow these instructions:
1. Turn off the transceiver by turning VOL/OFF control to OFF.
2. Set transceiver face down on the front panel handles.
3. Undo the two latches, located on the side of the transceiver to unlatch the
battery case from the transceiver.
4. Pull the battery case straight up and away from the transceiver.
5. Remove the used batteries from the transceiver by pulling straight up.
6. Plug new batteries into the transceiver.
7. Slide battery case over the batteries and into the rear skirt of the transceiver,
fastening it into place with the two latches.
3-2.3. ATTACHING AND REMOVING THE HANDSET
Attach
the handset to the HDST connector. The O-ring seal on the handset may require
considerable exertion before rotating the mating connector clockwise into a locked position.
3-2.4. ATTACHING THE ANTENNA
3-2.4.1
Attaching the Antenna
Before attaching the UVU-100 LOS antenna to the transceiver, verify the ball and swivel joint
at
the mounting base of the antenna is free to swivel. If it is not free, then loosen the swivel clamp
ring from the collar ring. These two rings are located at the antenna base. With the ball and
swivel joint free to swivel, screw the antenna to the ANT connector with only the collar ring.
Exercise Extreme Care to prevent the threads on the collar ring from cross-threading with the
threads on the ANT connector. To set the antenna in a vertical position, tighten the swivel joint
clamp ring against the collar ring with the antenna in its proper position. With the swivel joint
clamp ring tightened, DO NOT use the antenna as a lever to cinch the collar ring to the ANT
connector.
