Warnings and Cautions

The instructions given in this topic involve connecting dangerous voltage to the radio and

should be carried out only by suitably qualified personnel.

A mains isolating switch should be fitted close to, and easily accessible from, the radio's

position. The isolation switch should isolate both live and neutral supplies, be clearly

labelled, and adequately rated to protect the equipment.

Four semiconductor devices used in the RF PA contain the toxic material beryllium.

Although no procedures in this documentation instruct semiconductor replacement,

equipment covers are removed exposing the devices. Users should be aware that there could

be a hazard should the output transistors become damaged.

Fig 4-1 shows the RF PA; the four semiconductors containing beryllium are outlined and have the

markings PAS1068, PAS1074 or PAS1075.
