1. INFRARED TRANSMITTERS - The HHM60 has
two locations for the IR transmitters. One at the
bottom of the microphone and one near the top. It is
important to keep one of these areas uncovered
when the microphone is in use so that the IR signals
will reach the sensor.
2. BATTERY CHARGING CONNECTOR - This
connector is located on the bottom of the unit. The
BC60 Battery Charger plugs into this connector to
charge the installed Nickel Metal Hydride (Ni-MH)
batteries. Do not attempt to use this charger if
Nickel Cadmium (Ni-Cd) batteries are installed as
the charging rate is too high for them.
UNDER NO
CIRCUMSTANCES SHOULD THE CHARGER BE
USED IF ALKALINE OR CARBON ZINC BATTERIES
ARE INSTALLED !
3.
BATTERY COMPARTMENT SLEEVE -
This
sleeve protects the batteries and microphone
adjustments. To remove it, unscrew it by rotating it
counterclockwise.
4. POWER LED - This LED lights green when
charged batteries are installed and the power switch is
turned on. The color changes to red when batteries
are low.
5. POWER SWITCH - This switch turns the micro-
phone on and off.
6. LO HI POWER SWITCH - This switch is used to
adjust the power applied to the IR transmitters.
Setting the switch on LO (down) will consume less
battery power but will give somewhat less IR range.
Setting the switch on HI (up) will extend the IR
range, but will cause the batteries to discharge
sooner.
7. CHANNEL SWITCH - The channel switch selects
between CH 1 and CH 2. If CH 1 is selected, the
CHANNEL A LED on the SRR60 Receiver will light
and the CHANNEL A Volume and Equalizer controls
will be used. If CH 2 is selected, the SRR60 CHAN-
NEL B controls will be active. The units are shipped
with the switch in the CH2 (B) position. If two
microphones are used it is important that one of
them be on CH 1 and the other on CH 2 so that they
don’t interfere with each other.
8. BATTERY COMPARTMENT - The battery
compartment is designed to hold two “AA” sized
batteries. Nickel Metal Hydride (Ni-MH) batteries
should be used so that they can be recharged
without taking them out of the unit. Nickel Cad-
mium (Ni-Cd) batteries can be used if they are
removed for recharging using an external charging
system. Carbon zinc or alkaline batteries can be
used in a pinch, but
NO ATTEMPT SHOULD BE
MADE TO RECHARGE THEM !
9. CHARGE CONTACT - The battery compartment
charge contact must make electrical contact with the
Nickel Metal Hydride (Ni-MH) battery installed in this
location so that charging can occur. If new cells are
purchased at retail, it will be necessary to remove
approximately 1/4 inch of insulation from the battery
installed in this location. If this is not done, the
batteries will not recharge when the charger is plugged
in. Do not attempt to charge other than the specified
Ni-MH cells.
