LZA2027 OPTION INSTALLED
The LZA2027 is a factory-installed option that allows connection to most
standard 8 channel or single tone remotes. The programming software
and cable is used to program up to 99 channels and the various features
into the remote. These features include: Go to Group ‘n’ Channel ‘n’;
Group Scan On, Group Scan Off; Channel Scan On, Channel Scan Off;
Priority Scan On, Priority Scan Off; Talk Around On, Talk Around Off;
Monitor On, Monitor Off; Off Hook, On Hook; and Next Channel.
The audio levels in and out of the LZA2027 might need some
adjustments once the base station is installed and the remote is
connected to the GBH-01 base station. See the Programming and
Service Manual (P/N 0300-30944-900) for making level adjustments.
A six pin modular jack is located in the rear of the GBH-01 chassis to
accommodate the tone remote interface cable. A 2 or 4 wire telephone
line is to be used to connect the remote to the GBH-01.
Warning: Do not plug the GBH into any Telco phone system. The GBH
rear modular jack is only used to connect directly to a compatible remote.
Go To Group “n” and Channel “n”
When the proper tones have been programmed into the remote for
respective channel and group assignment, any channel out of any group
can be selected from the remote. For example: Channel one on the
remote can represent Group 1, Channel 2 of the base station; Channel
two on the remote can represent Group 1, Channel 2 of the base station;
Channel three can represent Group 2, Channel 16 of the base station;
and so on. Up to 99 combinations of channel and group assignments can
be made. The GBH-01 is shipped from the factory with the LZA2027
programmed for channels one through eight in Group one.
The programming of the LZA2027 tones must match the remote. See the
LZA2027Programming and Service Manual (P/N 0300-30944-900) for
programming details.
Group Scan ON/OFF
This feature must be programmed into the LZA2027. Some remotes
have an auxiliary button that can be assigned to turn the Group Scan
function ON and OFF. See page 14 of this manual for an explanation of
the feature.
S
ELECT A CHANNEL
by turning the Channel Selector knob. After reaching
the highest number, the radio wraps to Channel 1.
The display can show channel numbers (numeric mode), channel labels
(alphanumeric mode), or receive and transmit frequencies. The display
mode and channel labels are programmed by the technician along with
group labels (if applicable) and channel frequencies. The display shows
slightly different indications during Channel Scan and Priority Scan
operation in alphanumeric and numeric modes.
TRANSMIT
P
RESS THE
PTT (Push To Talk) switch on the microphone. The TX
annunciator appears on the display and the red Transmit indicator
illuminates while the PTT is pressed. Talk in a normal voice with the
microphone approximately one to two inches from your mouth. Release
the PTT switch to stop transmitting.
If the TX annunciator does not appear and a tone is heard, you are on a
receive-only channel or the channel is busy (if Busy Channel Lockout is
enabled). Turn the Channel Selector knob to an authorized transmit
channel or wait until the channel is clear (if Busy Channel Lockout is
installed).
If the length of your transmission exceeds the preset time-out timer
setting, the transmitter automatically shuts off and a tone sounds. To
continue the transmission, release the PTT switch, and then press it
again and continue talking.
CODE GUARD OPERATION
