6.4.9 Tx Deviation Limit
NOTE:This alignment is required after replacing (or servicing) components on the transceiver board.
The Tx Deviation Limit alignment procedure limits the modulation of a baseband signal. It is used for 
primary modulation limiting. This procedure needs to be performed at multiple frequencies to allow 
for proper alignment across the entire RF band. The RF band is divided into frequency zones with a...

2. Left-click the highest frequency field first.
3. Left-click the PTT Toggle button on the screen to make the radio transmit. Wait 
approximately 5 seconds until the deviation/voltage displayed on the analyzer stabilizes. The 
screen indicates whether the radio is transmitting.
4. Adjust the deviation limit between 0.158 and 0.163 Vac on the R-2670 (2.785 to 2.885 kHz)....

6-18Radio Alignment Procedures: Mic Sensitivity Calibration
6.6 Mic Sensitivity Calibration
This procedure allows you to calibrate the microphone sensitivity level at each CPS setting 
(-12, -9, .... +9, +12), eliminating tolerances and deviations in the microphone hardware lineup 
circuitry. By tuning each CPS setting, the microphone sensitivity will be adjusted to exactly 3 dB 
difference between every 2 consecutive settings throughout the programmable range of the circuit....

Chapter 7 Encryption
7.1 Universal Crypto Module Kits
NOTE:This information applies to both conventional and trunked systems.
The encryption modules use a custom encryption IC and an encryption key variable to perform their 
encode/decode functions. The encryption key variable is loaded into the encryption module using a 
key variable loader (KVL). The encryption IC corresponds to the particular encryption algorithm 
purchased.
Table 7-1 contains the Universal Crypto Module (UCM) kits and their...

7-2Encryption: Load an Encryption Key
Whether the current personality is strapped for secure or clear, the secure status annunciator 
correctly displays the transmit operation as being either secure (encrypted) or clear (non-encrypted).
NOTE:You cannot change from secure to clear while the PTT button is pressed. The radio will 
generate an illegal tone and the transmission will be terminated.
Secure-equipped radios automatically determine whether a secure or clear voice message...

7.2.2 W4, W5, W7, and W9 Control Heads
To load an encryption key into a W4, W5, W7, or W9 control-head equipped radio:
7.3 Advanced Secure Operation
NOTE:The Advanced Secure feature is available only on radios that have been equipped by the 
factory to support it. The radio must also be equipped with an encryption module.
Advanced Secure incorporates the Multikey feature and a dual-encryption feature into the existing 
secure system....
