The first thing we need to do is choose three sub-audible tone/codes, one for each of our user groups.
We also need the Repeater Panel User number for each sub-audible tone/code we want to enable for
dispatch operation.
User Group Sub-audible Repeater Panel User #
Maintenance 127.3 Hz (User # 20)
Manufacturing 74.4 Hz (User # 04)
Security D031 (User # 54)
Application Note:
The Repeater Panel User database supports 154 user groups. The sub-audible decode is pre-
determined for each user group by its corresponding user number. Users 1 to 50 are CTCSS tones,
Users 51 to 154 are DCS codes. See “CTCSS Tones” and “Digital Squelch Codes” in Section 7 to
obtain the user number for dispatch operation.
Next we need to choose Interconnect User numbers for each of our user groups. This is the ID
number that callers will use to reach a user group. This number will be overdialed for Mobile-to-
Mobile calls and Phone-to-Mobile calls. In this installation we will only be using short sign-on, user
number placement can be anywhere.
• Maintenance 10 Dial 10 for Maintenance
• Manufacturing 20 Dial 20 for Manufacturing
• Security 50 Dial 50 for Security
We now have completed the necessary planning, prior to programming the Model 748 to support our
three user groups. First we will enable dispatch operation for Maintenance and Security in the
Repeater Panel User database. Next we will program the Interconnect User database to support short
sign-on.
To enable the Maintenance user group for dispatch operation on 127.3 Hz, select User range and set
the range to “20”. Verify that Decode is “127.3”. Set Enabled to “Yes”.

Select a command:
To enable the Security user group on D031 select User range and set the range to “54”. This selects
the Repeater Panel User number corresponding to D031. Verify that Decode is “D031”. Set Enabled
to “Yes”.
We now have CTCSS tone 127.3 Hz and DCS code D031 enabled for dispatch operation.
