EX7100 Technical Manual - Configuring the Terminal

Changing the Local Receiver Frequency.
Ensure the Receiver is set to operate on the required frequency.
Notes:
- This procedure is specific to terminals in their idle state. To change the Rx
frequency while a link is established, see 4.3.3.
- The EX7100’s front panel tuning range is limited. If a frequency change of more
than 100kHz
is required, it will be necessary to manually retune some parts of the
RF Section of the radio. Receiver module re-tuning instructions are detailed in
Sections 7.7.3 (VHF) and 7.8.3 (UHF). Duplexer module re-tuning instructions are
given in Sections 7.9.3 (VHF) and 7.10.3 (UHF).
In addition, it may be necessary to replace the Duplexer module if a large change
in frequency is required. Refer Section 7.9.4 (VHF) and 7.10.5 (UHF).
1) From idle, press ‘Enter’
Use the arrow keys to enter the First Level
password ‘1111’ and then press ‘Enter’.

→ is next to Rx Frequency.
Press ‘Enter’
4) The current frequency setting is displayed.
Press ‘Enter’ to change the frequency.
5) You will be asked for the Second Level
password. Exicom’s factory default is
‘1234’. If the default password does not
give access, see your System Engineer as
the password may have been changed
(refer to Section 3.4.1 for details).
6) The current frequency is displayed. Using
the arrow keys, change the frequency to
the required setting. Press ‘Enter’
(Note: When the cursor is under the least
significant digit, the frequency will
increment/decrement by the channel
spacing).
7) Press ‘Escape’ until the menu returns to
idle. The frequency change is now
complete.
