SAFETY
CAUTION
To comply with RF exposure requirements, a minimum separation distance of
20 cm (7.9 inches) is required between the antenna and all persons while the
transceiver is transmitting. ManPack (backpack) and hand-carry users should
not exceed 50% duty cycle, as this approaches RF hazard limits and reduces
battery life.
CAUTION
Several conditions must be observed when using the UVU-100 LOS antenna
mounted on the transceiver's front panel, as serious damage to the transceiver
may result if high RF power is allowed to leak into the interior of the transceiver
directly from the antenna.
1. Transmit ONLY with the cover of the transceiver securely fastened in place.
2. Use ONLY vendor supplied power supplies, such as the RF shielded battery
case (UBC-100) or power supply (UAC-100).
3. Use ONLY tempest approved shielded cables with the REMOTE connector.
CAUTION
When performing a self-calibration, the radio antenna port(s) must be attached
directly to a good 50 ohm load(s). BNC type loads are acceptable. Use of a
Type N to BNC adapter is recommended on the 30-90MHz antenna port (if
present). The use of attenuators (instead of 50-ohm loads) or cables between
load and antenna port can lead to calibration errors if there are strong RF
signals present. Failure to follow the above procedure can result in severely
degraded performance.
CAUTION
DO NOT attempt to change the operating frequency while the transmitter is
keyed on. Although the radio set will not be damaged, the radiated frequency
will be uncontrolled during tuning and can cause unnecessary interference to
other radio systems.

GeneralDynamics C4 Systems URC-200 (V2)
vi
CAUTION
DO NOT install the LOS antenna on the transceiver during testing in the
transmit mode with (1) the cover removed or (2) the transceiver powered from
an external power supply via test leads that are unshielded. RF from the
antenna can radiate into the transceiver, circumvent the protection loops, and
cause severe damage to the transmitter circuits.
WARNING
DO NOT THROW BATTERIES IN THE TRASH
Dispose of all used batteries in accordance with all manufacturer, Federal, State
and local laws and regulations.
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.

1.3.2.1 Transceiver - URC-200 (V2)
The transceiver is contained in cast-aluminum housing with all operating controls and connectors
located on the front panel. The battery connectors, for two batteries, are located on the rear panel.
The front panel components are protected by handles on the sides, and an extension on the top
cover protects the volume and squelch controls.
1.3.2.2 Antenna - UVU-100
CAUTION
To comply with RF exposure requirements, a minimum separation distance of
20 cm (7.9 inches) is required between the antenna and all persons while the
transceiver is transmitting. ManPack (backpack) and hand-carry users should
not exceed 50% duty cycle, as this approaches RF hazard limits and reduces
battery life.
The antenna is a 12-inch long, broadband, VHF/UHF vertically polarized antenna that is attached to
the front panel antenna connector. The antenna connector is a BNC type connector, surrounded by
a threaded sleeve. The antenna is screwed onto this sleeve.
1.3.2.3 Battery Case - UBC-100
The battery case holds two batteries. When replacing batteries, always use two of the same part
number. When replacing non-rechargeable batteries, always replace both. Refer to Table 2 for
compatible battery types, part numbers, and reference documents.

WARNING
DO NOT THROW BATTERIES IN THE TRASH
Dispose of all used batteries in accordance with all manufacturer, Federal, State
and local laws and regulations.
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.
Quick release latches enable the battery case to be securely attached to the unit for operation. When
the battery case is attached to the unit, the battery case is watertight. The case contains a vent to
permit venting of battery gasses.
1.3.2.4 Handset - H-189/GR
The handset contains a microphone and receiver for transmitting and receiving audio signals. A
retractable cord with a 5-pin connector attaches to the transceiver front panel. A push-to-talk switch
is located in the handset handle.
