CALL Light Function
If the CL200 (optional) Call Light button is pressed, or a call tone from an RTS or ClearCom intercom
system is received through the CL200 on the 2-wire circuit:
• One short beep will sound in the Speaker Station or headset, and will also be heard through all
Beltpacs or All-in-one Headsets registered to the same Base Station as the Speaker Station.
• The yellow CALL light next to the POWER button on the Speaker Station will flash 3 times and
pause, then flash 3 times and pause, then flash 3 final times.
Headset Microphone Gain Adjustment
Some users speak louder or softer than others. The headset microphone gain adjustment helps to
compensate for these differences, raising or lowering the voice level of the user speaking into the
microphone. Increase microphone gain for softer voices, decrease for louder voices.
• To adjust microphone gain, first be sure the internal speaker is off.
• Press and hold the ISO button while pressing the VOLUME up ▲ or down ▼ arrow.
― When you reach maximum microphone gain, you will hear “Maximum.”
― When you reach minimum microphone gain, you will hear a double beep.
There are 16 steps between maximum and minimum microphone gain levels.
Headset Sidetone Adjustment
Sidetone is the level of your own voice that you hear in the headset earpiece as you speak into the microphone.
• To increase or decrease the sidetone level, first be sure the internal speaker is off.
• Press and hold the IC button while pressing the VOLUME up ▲ or down ▼ arrow.
― When you reach maximum sidetone level, you will hear “Maximum.”
― When you reach minimum sidetone level, you will hear a double beep.
There are 5 steps between maximum and minimum sidetone levels.
NOTE: A trim pot is provided for fine tuning adjustments with a small screwdriver, through the hole labeled
SIDE TONE on the left side of the Speaker Station.
This adjustment only affects the level of your voice in your own headset, not how anyone else hears you.
Changing Batteries
When batteries are becoming weak, you will hear “Change battery” from the speaker or headset. When this
happens, remove the battery sled from the Speaker Station and replace the six batteries in it with fresh AA
batteries. Be sure battery polarity is correct when replacing the batteries.
Rechargeable BAT850 Batteries
If you are using the optional HME BAT850 Rechargeable Battery, remove the battery from the Speaker
Station and replace it with a fully charged battery. Recharge the battery in the optional AC850 Battery
Charger according to the instructions received with the charger. Charging time is approximately 3 hours.
Auxiliary Speaker Connection
An 8 ohm auxiliary speaker can be connected to the right side of the Speaker Station,
using the enclosed 2-position connector plug. Adjustments affecting the Speaker Station
will also affect the parallel auxiliary speaker.
