To receive a tone sequence, program the applicable tone format and per-
form the following steps:
STEP PROCEDURE

2. Turn MODULATION Select Control (3) to ''FM NAR''.
3. Enter the applicable RF Frequency (ref. paragraph 4-2-1 and
4-3-1)

[NOTE\
When decoding tone sequences, an ''R'' will only ap-
pear if the first tone received is the repeat tone:
lllclclriRI I
1~<1:
I21Jilil I I I I I l l
In all other sequences, the repeat tone will be
automatically decoded as the preceeding digit; e.g.:
lllclclrl,l<l I 1, 9 1 : 1212121 I I I I I l l
Compliance with the following will avoid confusion
in the decoding process:
1. Do not execute the receive option when there is
activity on a receive channel.
2. When decoding sequential numbers or when a poor
signaling environment is present, the code should be
entered several times to eliminate the possibility of
error.
