RECEIVER OPERATING INSTRUCTIONS

Before operating a receiver, one or more IFB T1 transmitters must be placed in XMIT mode, with each transmitter set to

the desired frequency and connected to a proper antenna, audio source, and power source. The transmitter frequency

block must be the same as the receiver frequency block as marked on each unit.

RECEIVER NORMAL OPERATION (already programmed)

1. Plug an earphone or headset into the 3.5mm jack and set for MONO PLUG or STEREO PLUG. Be sure the unit

has a good battery.

2. Rotate the knob clockwise to switch the power ON (Do NOT hold the knob in while switching power ON). The LED

will blink corresponding to the channel number (1 thru 5). Rotate the knob to set the desired audio level.

3. To change channels, depress the knob briefly and release. The LED will blink the next channel number and the

receiver will resume operation on that channel.

4. When power is switched OFF, the unit remembers the channel and will return to the same last used channel

number when switched back on.

PROGRAMMING - ADD A NEW FREQUENCY TOTHE NEXT OPEN CHANNEL

1. Position the receiver at a location within 20 to 100 feet of the transmitter or transmitters.

2. With the power ON, depress the knob until the LED starts rapidly blinking, then release the knob.

3. The unit goes into program mode and does a scan/search. Previously programmed frequencies will be automati-

cally skipped. When the unit stops on a new frequency audio from the transmitter will be heard in the earphone

and the LED will stop blinking rapidly and will change to a slow blink mode. (Note: In units below serial number

850 the LED will change to steady ON, no blink.)

The unit is now waiting for an operator decision. You must now decide to either SKIP or STORE the frequency

(step 4 or 5 below.) Switching the power to OFF without storing will delete the frequency.

4. To SKIP the frequency, depress the knob briefly and the scan/search will resume.

5. To STORE the frequency into a channel memory, depress the knob until the LED blinks the new channel number,

then release the knob. The frequency is now stored in an open channel.

6. The unit will continue scan/search for other frequencies. To store more frequencies repeat steps 4 and 5 above.

Up to 5 frequencies can be stored in memory channels.

7. When all desired frequencies are stored switch the power to OFF for a few moments, then switch back to ON. The

unit will blink the last stored channel number and resume normal operating mode on the last channel stored.

8. The first scan is made at low sensitivity and searches for only high level transmitter signals to avoid intermods. If

the receiver does not stop on any frequency in the first scan, that means an IFB transmitter was not detected. In

this condition the LED will change from a fast blink to a slow blink indicating the end of the scan (the LED will

remain steady ON in units below s/n 850). The complete scan should take 15 to 40 seconds.

9. If the receiver still does not stop on any frequency, check that the transmitter is ON. Also, if a frequency is not

received or received but distorted, some other signal may be interfering on that frequency. Change the transmitter

to another frequency and try again.

A second scan at high sensitivity is initiated by depressing the knob briefly at the end of the first scan to search

for low level transmitter signals. When the scan stops and the transmitter audio is heard, either SKIP or STORE

the frequency (step 4 or 5 above).

10. Switching the POWER to OFF during any mode simply terminates that mode and returns the unit to normal

operating mode when the power is switched back to ON.
