Radio Transmit Level Adjustment Procedure
Note: A radio service monitor is recommended for this adjustment.
1. Connect at least one belt station to the U9922-G38(EU) gateway and ensure sidetone
is present (see belt station User Manual).
2. Open the cover of the U9922-G38(EU) and find the large silver knob.
3. Press and hold the PTT and speak clearly and loudly into the microphone.
4. Slowly turn the knob until the radio service monitor reads 4.0-4.5kHz deviation.
a. Clockwise to increase level; counter-clockwise to decrease
Radio Receive Level Adjustment Procedure
1. Connect at least one belt station to the U9922-G38(EU) gateway and ensure side-
tone is present (see belt station User Manual).
2. Open the cover of the U9922-G38(EU) and find the large silver knob.
3. Tune the radio to a continuous transmission (such as NWS) or transmit a test signal
from another radio.
4. Adjust the volume control on the radio to a level slightly higher than typical.

Range
The range of a belt station and a gateway can be up to 300ft (100m). If you are in an
environment with metal or concrete walls, this range could be reduced. If the belt station enters
into a "fringe" reception area, a brief sequence of three beeps will be heard in the headset. This
is to serve as a warning of a possible disconnection if conditions are not improved. When
possible, the user should attempt to regain line-of-sight contact with the controller. When the
belt station travels out of range of the gateway, a voice alert will indicate that the connection has
been lost. To reconnect, simply move back into range and connection with the gateway will
automatically be reestablished, also noted by a voice alert.

In some circumstances it may be necessary to “purge” the U9922-G38(EU) of some of its linked
belt stations. Typically purging is not necessary unless there are multiple gateways in the same
vicinity and you wish to remove a belt station from this gateway and link to a different gateway.
A gateway can link up to six belt stations where a belt station can be linked to only one gateway
at a time.
