1. EMITTER CONNECTOR -

2. POWER ON LIGHT - This

LED is illuminated green

whenever charged batteries are

installed and the POWER

switch is turned on. When

batteries are low, the color will

change to red.

3. POWER SWITCH - This switch turns battery

power on and off.

4. BATTERY CHARGE CONNECTOR - 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 Cad-

mium (Ni-Cd) batteries are installed as the charging

rate is too high for them.

UNDER NO CIRCUM-

STANCES SHOULD THE CHARGER BE USED IF

ALKALINE OR CARBON ZINC BATTERIES ARE

INSTALLED!

5. ADJUSTMENT TOOL - This tool nests just

above the Channel Switch (8) and Mic. Gain controls

(10), and is used to set the Power and Channel

switches and to adjust the Mic. Gain control.

6. LO HI POWER SWITCH - This switch is used to

adjust the power applied to the IR transmitter in the

Lavaliere mic/IR transmitter. Setting the switch on

LO (left) will consume less battery power but will

give somewhat less IR range. Setting the switch on

HI (right) will extend the IR range, but will cause the

batteries to discharge sooner.

7. 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 !

8. CHANNEL SWITCH - The channel switch selects

between channel 1 (A) and channel 2 (B). Units are

shipped with the switch set to channel 1 (A). If

channel 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

channel 2 is selected, the SRR60 CHANNEL B

controls will be active. If two microphones are used

it is important that one of them be on channel 1 and

the other on channel 2 so that they don’t interfere

with each other.

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. 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.

10. MIC. GAIN - This control varies the level of

modulation of the signal that occurs when the

lavaliere wearer is speaking. Too low a setting will

result in inadequate audio output from the speakers.

Too high a setting can result in acoustic feedback

(howl) or audio distortion. The correct setting must

be determined by experimentation and may very

from one instructor to another.

The Lavaliere Mic/IR Emitter

plugs into this connector as

shown in the photo at right.
