ferris: P42; Personal Portable Radio

The following information appeared in Ferris Service Bulletin of 10 October 1971.

A poor copy of the relevant part of that Service Bulletin is attached. The image (Fig 3) is of acceptable quality.

3. Breakage of Resistor R10 – Model P42 

In some cases movement of the battery has caused breakage of Resistor R10. There have also been some instances of the battery terminal contacting the anode lead of Diode D1. When Model P42 radios are received for service, it is advisable to carry out the following preventative modifications. (refer FIG 3).

a)     Remove and relocate Resuistor R10 below the printed circuit board.

b)    Unsolver the anode lead of Diode D1. Slip a length of insulating tubing over this lead. Resolder.
