Maxon SP200/210 Radio

4.5 Alignment

CAUTION

This radio contains static sensitive devices. Static safe precautions should be observed, in particular we would recommend the use of a suitable floor mat, table mat, bonding cords and a wrist strap. The soldering iron should have an earthed tip.

Care should be exercised in the handling of static sensitive components and they should always be transported in the correct containers.

Never remove, or insert, static sensitive devices with the power applied.

4.5.1 Preparation
