Service Hints

Problem Possible Solution

Audio can be heard from the remote, but

the display is blank and the remote LED

on the radio interface keeps blinking.

The polarity of the data lines is probably backward. Change

the position of JP7 in the radio interface.

Audio can be heard on the remotes, but a

Supervisor remote is muted when another

remote enters privacy mode.

Check jumper JP3 on the Supervisor remote main PCB. It

should be in position B.

The In-Use icon is not visible on the

display, but the remote cannot enter

privacy mode.

If another remote can enter privacy mode, check the JP5

jumper on the keypad PCB of the faulty remote. The

jumper should not be cut (see the Installation section). If no

other remote can enter privacy mode, enable privacy mode

in system programming.

A fuse blows. A blown fuse can indicate that something is not connected

correctly. Check the power connections and the polarity of

connectors.

The following fuses are used in the units:

Remote: 1 A, AGC, fast blow

(Zetron Part No. 416-1576)

Radio Interface: 0.5 A, AGC, fast blow

(Zetron Part No. 416-1200)

In case of further difficulty, contact Zetron technical support. Please have the serial

number of the unit and/or the Zetron order number ready. If the call is made from the

installation site by the installer or radio technician, the problem can usually be solved

over the telephone.
