INSTALLATION AND CONNECTIONS
Selecting a location
Select a location for the transceiver that allows
adequate air circulation, free from extreme heat, cold,
or vibration, and other electromagnetic sources.
Never place the transceiver in areas such as:
• Out of the specifi ed temperature range for the
controller (0°C ~ 50°C, 32°F ~ 122°F) and the RF
unit (–10°C ~ +55°C, 14°F ~ 131°F).
• An unstable place that slopes or vibrates.
• In direct sunlight.
• High humidity and temperature environments.
• Dusty environments.
• Noisy environments.
Heat dissipation
• NEVER install the transceiver in an insecure place
to avoid touching the heat sink on the controller’s
rear panel and the RF unit and to avoid operation
by unauthorized persons.
• NEVER install the transceiver in a place without
adequate ventilation. Heat dissipation may be
reduced, and the transceiver may be damaged.
• DO NOT place the transceiver against walls or put
anything around the transceiver. This may block
airfl ow and overheat the transceiver.
Connecting a microphone
Plug the microphone into the [MIC-SP] jack and the
[MIC] jack, and attach the microphone’s cable to the
microphone plate to avoid cable breaks.
L
Confi rm that the transceiver is OFF before connecting or
disconnecting optional equipment.
1. Attach the microphone’s split ring to the plate.
2. Plug the microphone into the [MIC-SP] jack and
the [MIC] jack.
(MIC-SP: 3.5 mm (1/8 inch), MIC: 2.5 mm)
Attaching the cushions
Attach the cushions, as illustrated below.
Cushion Sheet
(Supplied with the transceiver)
L
When you connect other devices to the [MIC-SP]
jack and the [MIC] jack, attach the cable to the plate
through the split ring (User supplied).
Microphone plate
CAUTION: Hot surfaces. DO NOT touch
the transceiver’s surface after continuously
transmitting for long periods of time. The
transceiver’s chassis radiates heat, and it will
become hot to protect the power amplifi er
unit from overheating. Touching it may cause
a burn.
[DC 13.8 V]
Accepts regulated DC power of 13.8 V DC ±15%
through the supplied DC power cable.

WARNING!
• NEVER reverse the DC power cable polarity.
• NEVER remove the fuse holder on the DC power
cable.
• NEVER use other than specifi ed DC power cable.
• NEVER modify, bend by force, twist, pull or heat
the DC power cable.
• NEVER put something heavy on the DC power
cable.
