Radio Tuning Procedure

7.0 Radio Tuning Procedure
7.1 General
The recommended hardware platform is a 386 or 486 DX 33 PC (personal computer) with 8 MBytes
RAM, MS DOS 5.0, Windows 3.1, and RSS (Radio Service Software). These are required to align
the radio. Refer to your RSS Installation Manual for installation and setup procedures for the
required software; the user manual is accessed (and can be printed if required) via the RSS.
To perform the alignment procedures, the radio must be connected to the PC, RIB (Radio Interface
Box), and Universal Test Set as shown in Þgure 3-9.
All tuning procedures are performed from the Service menu.
Before going into the Service menu, the radio must Þrst be read using the File / Read Radio menu (if
the radio has just been programmed with data loaded from disk or from a newly created codeplug,
then it must still be read so that the RSS will have the radioÕs actual tuning values).
All Service windows read and program the radio codeplug directly; you do NOT have to use the RSS
Read Radio / Write Radio functions to program new tuning values.
CAUTION:
3-8
Figure 3-9 Radio Alignment Test Setup.
DO NOT switch radios in the middle of any Service procedure. Always use the
Program or Cancel key to close the tuning window before disconnecting the radio.
Improper exits from the Service window may leave the radio in an improperly
conÞgured state and result in seriously degraded radio or system performance.
