Performance Checks: RF Test Mode4-3
To enter test mode:
1.Turn the radio on.
Within ten seconds after the self test is complete (self test tone is heard), press SB2 (Side Button 2 in 
Figure 4-2) five times in succession. If the self test complete tone is not heard, see Error Codes 
information in Chapter 9. Entry into the test mode is indicated by a positive indicator tone followed by 
a good key chirp (GKC) upon entering test mode, the radio is in the carrier squelch mode....

Chapter 5 Radio Alignment Procedures
5.1 Introduction
This chapter provides an overview of the Commercial Series Customer Programming Software (CPS) 
and the Global Tuner as designed for use in a Windows® 98/NT4/2000/ME/XP environment. Both 
cover all the functions of the traditional Radio Service Software (RSS) package.
They are both available in the CPS and Global Tuner (CD ROM) Kit (RVN4191). 
5.2 CPS Programming Setup
Refer to online help files for the CPS Programming procedures. (See Figure 5-1 for...

5.3 Radio Tuning Setup
A Windows 98/NT4/2000/ME/XP PC (personal computer) and Global Tuner are required to tune the 
radio. To perform the tuning procedures, the radio must be connected to the PC, RIB (Radio Interface 
Box) and Universal Test Set as shown in Figure 5-2 below. Refer to online help files for the tuning 
procedures.

5.4.1 Reference Oscillator Warp
This is an important operation which affects all deviation values such as DTMF, MDC1200 Signaling 
etc. The frequency will drift if not warped properly. Perform this operation prior to all other transmit 
tuning operations in order to...

1.Under Tx Align menu, select Reference Oscillator Warp (Figure 5-3).
2.There is only 1 frequency point shown which is always the last non-0 transmit frequency point, 
which will normally be F7. 
3.Click on the slider thumb and press PTT Toggle to key up the radio at the corresponding fre-
quency point. 
4.Monitor the transmit frequency. 
5.Adjust the slider, spin or edit control (press ENTER to confirm selection/send a...

Radio Alignment Procedures: Transmitter Alignment Options 5-5
Compensation alignment balances the modulation sensitivity of the VCO and reference modulation 
(synthesizer low frequency port) lines. The compensation algorithm is critical to the operation of 
signaling schemes that have very low frequency components (Digital Private-Line) and could result in 
distorted waveforms if improperly adjusted. To perform Modulation Balance tuning, follow the 
following steps. 
1.Under the Tx...

5-6Radio Alignment Procedures: Transmitter Alignment Options
Note:When checking the RF power output of the radio with a test set, always use a pad of 
at least 30 dB attached to the radio end of the RF cable. This will avoid an RF 
mismatch and ensure a stable RF reading that will not change with varying lengths of 
connecting cable
