7. Input GAIN Control - This control adjusts the transmitter input sensitivity to work
with microphone and instruments inputs. For optimal performance, using the
included screwdriver, set the input GAIN control to where you see the CR288
PEAK indicator start to light under high levels, then turn down slowly until the
PEAK light stops lighting.
8. Battery Holder - Insert two standard AA (LR6) batteries here, being sure to
observe the plus and minus polarity markings shown. Although rechargeable
Ni-Cad batteries can be used, they do not supply adequate current for more than
four hours. WARNING: Do not insert the batteries backwards; doing so can cause
severe damage to the CB288 and will void your warranty.
9. IR Lens - This window is used to capture the infrared signal sent from the CR288
during the IR SET to channelize the transmitter.
10. Screwdriver - Designed for use in adjusting the CB288 input GAIN control (See
#7 Input GAIN Control).
11. Channel Designation - Identifies the receiver channel that the belt pack syncs and
