Programming Transmitters
To program the transmitter to the frequency of the receiver:
1. Switch power to the receiver ON and select a clean frequency or
GROUP/CHANNEL on the receiver. The "PRG IR" menu appears on
the display:
i Refer to fig. 4 on page iv.
2. Set the ON-MUTE/PRG-OFF switch (19) to "MUTE/PRG". The display
will alternately indicate the currently selected frequency and "PRG IR".
i Refer to fig. 11 on page v.
3. Point the infrared sensor (1) on the transmitter at the infrared emit-
ter (2) on the receiver from a distance of 4 inches (10 cm) max.
4. On the receiver, select "IR PRG" to start the programming process.
IR OK: The transmitter has been tuned to the same frequency as
the receiver.
IR ERR: The data transmission has failed (no communication).
TXBAND: The frequency bands of the transmitter and receiver are
not identical.
Multichannel Systems
•
Be sure to assign a separate carrier frequency to each wireless
channel (transmitter and receiver).
•
To find inter-modulation-free carrier frequencies quickly and eas-
ily, we recommend using the "AUTO" menu to select all required
carrier frequencies from the same Frequency Group.
•
Do not operate two or more wireless channels on the same fre-
quency at the same time and location. This would cause unwanted
noise due to radio interference.
Battery Management
To make sure the transmitter battery capacity is indicated correctly:
•
Do not use any dry or rechargeable batteries other than the types
listed below.
•
Never use batteries that have been in use during the previous 24
hours.
•
Match the transmitter system to the type of battery you inserted:
1. Select the "BAT.TYP" menu. The current setting starts flashing.
2. Use the arrow keys to select the desired setting:
"AUTO": The transmitter automatically identifies the battery type.
Weak or very old batteries may cause the remaining battery life
to be displayed incorrectly. In this case, use the correct setting for
your battery (see below):
"LR6" for AA size (LR6) alkaline dry batteries. The display indicates
this battery type and its remaining capacity in hours like this: "L
5h" (example).
"FR6" for AA size (FR6) lithium batteries. The display indicates
this battery type and its remaining capacity in hours like this: "F
10h" (example). Lithium batteries have a life of up to 14 hours. The
display, however, will only indicate a maximum of 10 hours. With
new lithium batteries, the display will constantly indicate "F 10h"
during the first four operating hours.
"NiMH" for AA size (HR6) NiMH rechargeable batteries. The dis-
play indicates this battery type and its remaining capacity in hours
like this: "H 6h" (example).
3. Program the assigned transmitter referring to the section on
"Programming Transmitters".
i
Since the chemical parameters of batteries take some
time to stabilize, the system may correct the battery
indication (type and remaining capacity) about 10 to 30
minutes after switching power to the transmitter on.
4. ADVANCED FUNCTIONS
(EXTRA MENU)
The EXTRA menu provides the following functions:
NAME
receiver ID
STATUS status and warning messages
RHSL
rehearsal function for finding dropouts
SQL
squelch threshold
PILOT

Receiver ID
The "NAME" screen lets you edit the existing name of the receiver.
If you have not stored a receiver name yet, you can use the "NAME"
screen to assign a new name to your receiver. The receiver name may
be any combination of up to six letters and/or numbers.
1. Select the "NAME" menu. The first character start flashing.
2. Use the arrow keys to select the desired characters.
Status and Warning
Messages
The "STATUS" screen lets you activate a visual warning that alerts you
to selectable critical system conditions. If one of the selected condi-
tions occurs, the display back-lighting will change from green to red
and a warning message will appear on the display that describes the
current condition. The warning messages appear in order of priority:
1. "LOW.BAT": Transmitter battery capacity is low. The battery will
be dead in about 60 minutes.
2. "AF CLIP": Audio overload. The received audio signal drives the
receiver into clipping.
3. "RF.LOW": Received signal field strength is so low that the receiv-
er audio output has been muted to suppress unwanted noise.
All selected warning functions are active in both LOCK and SETUP modes.
