5.2 Series II Radio Tuning

This section covers some basic Series II base station modules radio tuning and verification for:

VHF (T83x-xx-0200),

UHF (T85x-xx-0250) and

800 MHz/900 MHz (T88x-xx-0200).

Note:

Usually, this section is not done unless called for in section 5.1 “Series II - Radio Programming”

or in

Table 9

“Checklist B” (General).
