Handheld Transmitter set-up:
1. Before setting up the transmitter, please refer to the RE-2/FMR-500
Receiver manual . If the receiver has been set up, continue to step 2.
2. Install a fresh Alkaline Battery into the transmitter.
3. Insure that the Microphone Gain Control is set at about 50 % of
rotation or less.
4. Place the Power Switch in the ON position.
The Red Low Battery Light (“Batt”) near the display should “flash”
one time if the battery is good. If the light remains on, the battery is
weak and should be replaced. No flash at all indicates a dead battery
or no battery installed.
5. The screen should display the GP (Group) and CH (Channel) screen. If
the Group and Channel agree with the receiver Group and Channel,
proceed to the next step. If the Group and Channel do not agree with the
receiver, or you wish to change them for any reason, proceed with this
step. Press the SET switch one time. The GP number will start
flashing. Use the UP (arrow) switch to increase the Group or the Down
(arrow) to decrease the Group number. Press Set when the Group
desired is displayed. The Channel number will now be flashing. Use the
Up or Down arrow to select the desired channel. Press Set when the
Group and Channel is selected.
6. Monitor the RE-2/FMR-500 Receiver operating screen. Note that the
RF (1-100) Bar Graph should indicate near the 100 bar if the transmitter
is close to the receiver. The AF Bar Graph should show very little or no
indication until you talk or sing into the microphone. Adjust the Gain
Control (small screwdriver adjustment located in the hole between the
display and the microphone element) if necessary, to cause the AF bar
graph to peak near –3 but not over +3 for best performance.
7. If you are satisfied with the Group/Channel and AF screen displays,
the mixer or sound system gain/volume can be increased to monitor
the sound. The Handheld System is now ready for use.
8. Switch the Power off when use is complete.
