General Check
(1) Main unit and pre-amplifier
① Turn on the main unit.
② Press the menu switch .
③ Tap Equipment setting.
④ Make a note of the radio channel number under
Common setting.
⑤ Turn on the pre-amplifier and verify that the
green LED is lit and the radio channel of the
main unit matches the description in "(2) Radio
channels" in "2-3 Explanation of Pre-Amplifier
LEDs" on p. 17.
If the radio channels do not match, tap the radio
channel under Common setting to change it.
⑥ Verify that the console shows an icon of the
same color as the pre-amplifier. If the icon is
not displayed, the main unit is not receiving the
radio signal.
Check the following:
● If the radio signal is not being received due to
the surrounding environment, tap the radio
channel under Common setting to change it as
described earlier.
● If the radio unit on either the pre-amplifier or
the main unit is faulty, check another unit in
the same way to determine whether the
problem is specific to the pre-amplifier or the
main unit. If the problem is with a specific
pre-amplifier, try replacing the antenna or
extension cable.
⑦ Make sure the data arrival rate is not 0.
If the data arrival rate is between 0 and 50, it is
possible that the radio signal is not getting
through due to the surrounding environment.
Tap the radio channel under Common setting to
change it as shown at left.
