S-COM 6K Owner's Manual page 40

1. INTRODUCTION
Your controller uses messages to communicate with both the users of your repeater and the
programmers of the repeater controller. Messages may be composed of combinations of CW
(Morse) characters, beeps, DTMF characters, and various paging formats. Most of the controller's
messages are remotely programmable via DTMF commands.
2. MESSAGE ADJUSTMENT POTS
Three of the 6K's eight pots are associated with messages. The three pots are:
CW (R77)
PAGE (R78)
DTMF ENC (R79)
All pots adjust clockwise to increase level, and adjust counter-clockwise to decrease level.
CW level is typically set to a low level of deviation (500 Hz to 1.5 kHz). CW identifications must be
recognizable, but they should not interfere with voice conversations.
Page levels are typically set to a high level of deviation (3.0 kHz to 3.3 kHz) so they can reliably trip
pagers.
DTMF level should be set per the requirements of your DTMF receiving equipment. High levels
should be avoided to minimize twist problems. Note that the level of DTMF characters sent to the
phone line when dialing is not adjustable. This level is fixed in accordance with FCC Part 68 rules
and regulations.
When sending tone pages, the controller can acknowledge by sending the page to the phone line.
This level is the same as the CW level.

MESSAGES
Adjusts the level of the CW generator. Adjusting R77 will affect the
CW level going to the transmitter and the CW level going to the
telephone line.
Adjusts the level of the page tone generator. Adjusting R78 will
affect the level used for 1-tone, 2-tone, and 5/6-tone pages to the
transmitter.
Adjusts the level of the DTMF generator when sending DTMF pages
to the transmitter. Does not adjust the level of DTMF digits when
dialing the phone.
