4-2.2. RECEIVER TESTS
WARNING
DO NOT THROW BATTERIES IN THE TRASH
Dispose of all used batteries in accordance with all Federal, State
and local laws and regulations. Lithium batteries may be used in
the URC-200 (V2) Transceiver however lithium batteries contain
hazardous materials.
Improper handling, reverse-current operation or high
environmental temperatures may cause internally generated heat,
fire or toxic materials and gasses to be released from the battery.
The following precautions must be strictly observed to prevent
injury to personnel or damage to equipment:
 DO NOT heat, incinerate, crush, puncture, disassemble or
mutilate the batteries.
 DO NOT recharge primary Non- rechargeable) batteries.
 DO NOT store in equipment during periods of non-use for
more than 30 days.
 DO follow all safety instructions that come with the batteries or
printed on them.
 TURN OFF the equipment immediately if you (1) detect that
the battery compartment is becoming unduly hot, (2) hear battery
cells venting (hissing), or (3) smell irritating sulfur dioxide gas.
Remove the battery only after it is cool (after 30 to 60 minutes),
and dispose of it by following approved procedures.
The following tests evaluate the performance of the receiver circuits. The functions that will
be tested are receiver sensitivity and distortion at various frequencies in AM and FM, and in CT
and PT modes. Squelch sensitivity will also be checked. If the transceiver fails any of the tests, or
if it cannot be adjusted to specified values, it must be sent to General Dynamics C4 Systems for
repair.
4-2.2.1 FM PT Sensitivity and Distortion
1.
Set up the test equipment as shown in Figure 4-1. Connect the
VERT/SINAD/DIST/DVM/COUNTER IN connector on the R2600 to Pin E (PT
OUT) of the Breakout Box. Pin A or D of the remote connector is return
ground.
2. Set the input power supply to 28  0.1 Vdc.
