ALIGNMENT PROCEDURE
SUGGESTED TEST EQUIPMENT
• WARNING: Any repairs or adjustments should be made under the supervision of a certified technician.
The following equipment, or its equivalent, is required for proper alignment of the UHF synthesized mobile radio:
1. Termaline watt meter or Through-line watt meter with termination into 50 ohm dummy load.
2. AC/DC VOM with a minimum of 1 Megohm input impedance.
3. SINAD Meter.
4. FM Communications Monitor.
5. Regulated power supply capable of 9 to 16 volts adjustable; at least 10 ampere capability.
6. Oscilloscope.
7. Audio Distortion Meter (desirable but not necessary).
8. Frequency Counter.
PROGRAMMING FOR ALIGNMENT
For the alignment procedures the EEPROM should be programmed as follows:
1. An EEPROM should be programmed with 3 transmit and 3 receive frequencies.
2. The lowest and highest frequencies should enclose the user’s frequencies and be 10 MHz apart. The lowest
and highest frequencies must be within the appropriate frequency band.
3. In addition to programming frequencies, CTCSS and DCS codes must also be programmed to insure that
the modulation deviation for these potential options is correct, even if they are not to be used for the
customer’s operation. The following format should be used:
Lowest RX/TX frequency 67.0Hz CTCSS Tone
Middle RX/TX frequency DCS Code 072
Highest RX/TX frequency 250.3Hz CTCSS Tone
Highest RX/TX frequency No Tone Options
MONOGRAM SERIES LBI-38865
