All the above models have certain features in common. Each has a variable rotary
volume control which is also the main power on/off switch. There is also a continuous
reading, Battery Condition Indicator Light on the back of every unit. And, with an Earmark
portable radio, you always have the ability to actuate the transmitter with a Push To Talk
(PTT) Switch or let the transmitter run all of the time.
II SETUP
As received, your new Earmark ValComm 900 Headset is ready for use in a typical,
industrial operating environment. Only a few items require your attention before you
start operations.
A.
BATTERIES
Your Headset comes with rechargeable NiMh batteries. This power system should last
approximately 16 hours when fully charged. The headset should be charged immediately
when you receive it.
To recharge the headset, plug the power supply that came with your headset (see
specs on back page) into the charging jack at the bottom of the side with the microphone.
A charge session of 7-8 hours should completely charge the batteries. The LED next to
the charging jack will stay a red or amber color as long as the charger is attached and
functioning. If the light is amber, the headset is turned on... you should turn the headset
off in order to charge faster.

E. OUT OF RANGE INDICATOR
When you are out of range of the other ValComm 900 headset in your group, you will
hear a sound in your ear that goes from high to low frequency. Immediately get closer to
the other person or base. When you are back in range you will hear a sound which is
low to high frequency.
This condition will not happen suddenly... you will have warning that you are drifting out
of range when you hear sound quality begin to degrade.
