WARNING!

USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE.

USE AS LOW A VOLUME AS POSSIBLE.

In order to use this system safely, avoid prolonged listening at excessive sound pressure levels. Please use the following guidelines established by the Occupational Safety Health Administration (OSHA) on maximum time exposure to sound pressure levels before hearing damage occurs.

90 dB SPL at 8 hours 95 dB SPL at 4 hours 100 dB SPL at 2 hours 105 dB SPL at 1 hour

110 dB SPL at 115 dB SPL at 15 minutes

120 dB SPL - avoid or damage may occur

It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In addition to the volume setting on the PSM, the SPL in the ear is affected by ambient sound from floor wedges or other devices. The isolation provided by the fit of quality earphones is also an important factor in determining the SPL in the ear.

/2 hour

Here are some general tips to follow in the use of this product to protect your ears from damage:

1. Turn up the volume control only far enough to hear properly.

2. Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels.

3. Have your ears checked by an audiologist on a regular basis. If you experience wax buildup in your ears, stop using the system until an audiologist has examined your ears.

4. Wipe the earphones with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing great discomfort or infection.

P4T TRANSMITTER FEATURES

TRANSMITTER FRONT PANEL

TRANSMITTER BACK PANEL

1. Local Earphone Output Jack (1/8 inch): Connects to earphones.

2. Local Earphone Level Control: This knob adjusts the volume of the

local earphone jack's amplifier. Always listen at low levels.

3. Input Level LEDs: Two vertical strings of four LEDs display the input

level of the left and right input channels. The four LEDs on the left display the status of the signal from channel 1 and the four LEDs on the right display the status of the signal from channel 2:

LED Signal Status

RED (top) Limiter Active

YELLOW (middle) Nominal Level

GREEN (bottom two) Signal Present

SET UP AND OPERATION

Follow these directions to set up the transmitter for operation.

1. Plug the power cord into the transmitter's DC INPUT power connector. Plug the other end of the power cord into a wall outlet.

2. Attach the antenna to the ANTENNA OUT BNC connector.

3. Connect line level outputs of an audio source into the audio INPUTS of the transmitter. Use both of the input jacks for a two-channel source. Use either input jack for a mono source. The P4T transmits in MixMode/stereo if both inputs are used, but automatically transmits in mono if only one input is used.

NOTE: All inputs are phantom power protected up to 50 VDC.

4. Select an operating frequency using the Frequency Select Button. Push the button repeatedly until the LED displays the desired chan-

PA715 ANTENNA

4. Transmission Frequency LED: This indicates which of the 16 chan-

nels (0-9 or A-F) is transmitting.

5. Frequency Select Button: This recessed button changes the trans-

mission channel. (Use a 1/4" plug to press this button.)

6. Antenna Connector 50 Ω, BNC type: This connects to the antenna

to transmit UHF signals to the receiver.

7. LOOP OUT Jacks: Two 1/4" TRS jacks allow the audio signal to pass

through the transmitter to other devices, including other transmitters, tape recorders, or amplifiers.

8. INPUT Jacks: Two 1/4" TRS switching jacks are line level audio

inputs.

9. DC INPUT Connector: Input for PS40 power cord.

nel. The display flashes. Push and hold the button until the flashing stops to confirm the change (use a 1/4" plug to press the button).

IMPORTANT: Never set more than ONE transmitter to the same operating frequency.

5. Once the P4T transmits audio, observe the input level LEDs. If the LEDs consistently illuminate red, decrease the output level of the audio source until the red LEDs flicker occasionally.

6. Set up the P4R receiver as directed in the P4R user's guide. Make sure that the frequency selected on the receiver matches the frequency selected on the transmitter.
