LED (1g) lights, reposition the receiver and/or transmitter such that field strength will increase back to optimum (OK LED (1g) illuminating).

6.The MUTE LED (1f) on the receiver illuminating means the squelch is active.

Remedies: Switch the transmitter ON or move closer to the receiver to the point that the MUTE LED (1f) will extinguish.

9.6.1. Multichannel Systems

If reception on the selected carrier frequency is disturbed, set the carrier frequencies for all channels up or down one or

two notches using the respective CHANNEL controls (1d, 2g, 3f) on each transmitter and receiver.

This is necessary to provide the minimum frequency spacing re- quired for intermodulation-free multichannel operation.

10. Cleaning

To clean the transmitter and receiver surfaces, use a soft cloth moistened with methylated spirits or alcohol.
