E0017 Tuning HBC Remotes

This Service Info applies to HBC radio remotes, models 730 and 735.

Under some conditions when a tele-teach battery is not available or cannot be used for tuning, there are alternate buttons located inside the receiver which can be used instead.

For Model 735 see below:

For model 730 (older versions):

The buttons are located on the underside of the top PCB boards in the receiver. By undoing 2 brass screws at one end of the top PCB boards, the 2 boards will swivel up and the buttons can then be seen on the underside.

On some 730 model transmitters, there are no contacts located inside the battery compartment to receive a tele-teach battery. In this instance, the buttons in the receiver are the only option to tune output voltages.
