Setting the
Headphone Volume
In order to ensure maximum reliability, the receiver setup functions are electronically locked
so it is not possible to change any settings unintentionally. The "LOCK" label is lit on the dis-
play.
• You can scroll through the following status screens:
- Preset (comes up only if a Preset has been saved): Carrier frequency shown as a Chan-
nel number within a Frequency Group.
- Frequency: Carrier frequency in MHz. (This screen is always available, even if no Preset
has been saved.)
- Headphone volume: curent headphone output level setting.
- Battery: Percent battery capacity. (This screen is only available if you are using a
BP4000 battery pack.)
In SETUP mode, the electronic lock is disabled so you can adjust all receiver parameters. The
"LOCK" label is not shown.
• To toggle between LOCK and SETUP modes, hold down the Setup control for about 2 sec-
onds.
• The receiver has no gain control. Therefore, in order to get optimum radio transmission,
you need to set the audio level on the transmitter, e.g., an HT4500 or
PT4500.
• To match the audio signal level to the input sensitivity of the camera, you need to set
the audio input gain on the camera. Check the camera manual for related instructions.
1. Switch power to the transmitter and receiver ON.
2. Set the audio gain on the transmitter to a low value.
3. Talk into the microphone as loudly as possible or aim the microphone at the sound
source to be picked up.
4. Increase the transmitter gain CAUTIOUSLY to the highest notch where the AF LED will still
remain green, without flashing red. This setting prevents unwanted noise and gives good
results.
• To get optimum results, set the audio gain as high as possible in order to avoid un-
wanted noise.
• If, however, you set the audio gain too high, you risk getting unpleasant-sounding dis-
tortion. Therefore, make sure to set the audio gain just high enough for the AF LED on
the receiver to indicate no overload - i.e., to remain green without flashing red.
In SETUP mode.
1. Call up the "Headphone Volume" menu.
2. The display indicates the current volume setting. Press the Setup control once. The dis-
played setting starts flashing.
3. Use the Setup control to select the desired volume level.
The displayed value indicates the relative volume level in dB. The maximum setting being
0 dB, lower levels are indicated by negative numbers. Between 0 dB and -48 dB, set-
tings are shown in 1-dB increments, lower settings in larger increments. The lowest se-
lectable level is -65 dB.
4. Press the Setup control once. The displayed setting is stored and stops flashing.
• In order to avoid hearing damage, make sure to follow the instructions in the
"High Volume" section.
