i20R Jumper Configurations
i20R Adjustments
Follow the instructions in the i20R Service Manual,
6880904Z40, to adjust the repeater operation. The TPL/
DPL level adjustment, with the “SIG” potentiometer, is
“touchy”. The input sensitivity of the Professional
Series radios makes adjustment to 15% to 20% of rated
system peak deviation rather difficult.
Ignition Sense Wiring
Adding the ignition sense lead to pin 10 of the 16-pin
connectors of the radios will ensure that the repeater
will automatically power-up whenever power is
applied. This is particularly important when the
repeater is mounted in a relatively inaccessible loca-
tion. Refer to Section 12, Ignition Sense Wiring, of this
manual.
NOTE
If you haven’t already done so, program
both of the radios for “Ignition Sense
Type:” as “On/Off & Ignition” or “Fol-
low Ignition Only” in the Accessory Con-

Configuration).
Professional Series Radio Adjustments
The application of the Voice and TPL/DPL from the
accessory connector of the Professional Series radios
requires a modification to the modulation calibration
of the radio.
NOTE
The maximum “voice” deviation of the
Professional Series radio must be
reduced to allow for the added TPL/DPL
signal that is generated by the i20R.
For example, consider an i20R repeater that is setup to
operate on 25 kHz channel spacing (maximum system
peak deviation equal to
±
5 kHz). If the TPL/DPL devi-
ation is
±
750 Hz, then the maximum deviation of the
Professional Series radio must be adjusted to less than
±
4.25 kHz in the Carrier Squelch mode.
The adjustment to the maximum “voice” deviation is
accomplished with the “Tuner” service software pro-
gram provided in the same disk set with the CPS.
WARNING
Failure to follow the above recommenda-
tion may cause the peak deviation to
exceed the maximum allowed by the
local licensing authority (the Federal
Communications Commission in the
United States of America) and result in
the issuance of a citation with possible
imposition of monetary fines.
