SERVICE INFORMATION:

It is important to follow 4 basic guidelines when installing a radio. In many cases where a newly-installed radio had been declared defective, subsequent examination of the vehicle and/or the radio chassis, disclosed certain installation shortcomings. This bulletin will remind dealership personnel that the following basic installation procedures should be followed.


1. RADIO CHASSIS MOUNTING SCREWS

Do not use radio mounting screws other than the ones supplied in the installation package. A screw that is too long will damage the radio's circuit board(s).

Figure 2:

2. RADIO BACK-UP FUSE

In many cases, complaints of "radio has no power...will not turn on" can be traced to a simple pre-delivery error of not installing the radio back-up fuse (Figure 2)

Figure 3:

Prior to testing the radio, verify that the Radio Back-up Fuse has been installed.

3. CASSETTE CAPSTAN LOCK SCREW

It is necessary to remove the capstan lock screw prior to radio installation. This screw is utilized to lock the capstan (protecting it from vibration damage) during transport. An identification tag is attached to this fastener (Figure 3).

4. ANTENNA GROUND CIRCUIT

If the radio has poor reception or static noise, especially noticeable in the AM band, check the antenna for a secure fit against the fender. The antenna locking nut must be thoroughly tightened to ensure a proper ground (Figure 4).
