Batteries and Battery Charging
If...
Test indicator lamp doesn’t illuminate when units are turned on...
Then...
• If rechargeable batteries are used, ensure that they have been allowed to
charge at least 14 hours to a full charge. Verify that the charging indicator
lamps are illuminated when the charging plugs are plugged into the units.
The units’ power switches must be in the “off ” position for charging.
• If the test indicator lamp still does not illuminate after a full charge, verify
that the system is operational by using a new alkaline battery. If the system
is operational with alkaline batteries, the rechargeable batteries or charger
may need to be replaced.
• The M-216 transmitter must be returned to COMTEK for service if the test
indicator lamp does not illuminate when new alkaline batteries are used.
Transmitter Audio Problem
If...
There is no visual indication on the “voice” modulation level indicator
when speaking into the microphone of the M-216 transmitter...
Then...
• Turn up the microphone gain setting clockwise until the voice
modulation indicator illuminates with speech level.
• Make sure the optional muting switch is in the “mic on” position.
• Check the CM-183RT microphone for a broken or frayed microphone
cord that may cause intermittent operation.
• Test the modulation indicator with the auxiliary audio input using a line
level signal and the CB-36ST auxiliary audio input cable to verify normal
operation. If the auxiliary audio input activates the voice modulation
indicator normally, the CM-183RT microphone may need to be repaired
or replaced.
• The M-216 transmitter must be returned to COMTEK for service if the
auxiliary input test does not activate the voice modulation indicator.
