THANK YOU FOR CHOOSING POLSEN.

This two channel wireless microphone system is designed for hands-free mobility in a wide variety of applications including video

production, electronic news gathering (ENG), electronic eld production (EFP), and classroom and presentation applications. The

portable receiver can be mounted on a standard shoe mount or attached with a belt clip� It is a reliable, easy-to-use solution for wireless sound transmission�

The CAM-2W includes an omnidirectional microphone (PL-2W) ideal for video applications� Omnidirectional microphones are less

susceptible to wind and clothing noise than cardioid microphones. The PL-2W affords exible placement options and allows for

head movement without affecting the sound� It can be readily placed on a costume, collar, or necktie� A tie clip is included�

The CAM-2WC includes a cardiod microphone (PL-2WC), which is ideal for presentation applications since it reduces room noise, allowing for greater distance from the source—making the system less susceptible to feedback�

The CAM-2W/2WC system was designed with two switchable frequencies to avoid interference while operating at a range of up to 100 feet (300 feet in optimal conditions)�

Included is a durable exible antenna that can be positioned for the best possible reception. Audio can be monitored in real time

with the included earphone�

Compander-Free System

The CAM-2 system is a compander-free system for delivering high-quality audio� The word compander is a combination of the terms

com

pressor and ex

in the receiver� Companding can cause undesirable artifacts such as the pumping and breathing associated with

compression. Compander-free systems don’t exhibit these artifacts, making them a favored solution among lmmakers around the world.

INSTALLING BATTERIES

The Transmitter and Receiver are each powered by a 9 V alkaline battery. Battery life is approximately 8 hours of operating time.

For installing batteries into the Transmitter and Receiver:

1. Remove the Battery Compartment Cover by pressing down and sliding the compartment in the direction of the arrow�

2. Place the cap snuggly over the battery terminals�

3. Place the Ribbon on the bottom of the compartment with enough temporarily draped over the edge so it can be tugged to dislodge a spent battery later�

4. Place the battery and cap into the compartment making sure that it is fully seated�

5. Replace the Battery Compartment Cover� Make sure the cover slides into place easily�

6. Note: To avoid possible damage, batteries should be removed if the unit will not be used for a lengthy amount of time�

7. Alternatively, the receiver can be powered by a 9 V DC power supply (not included)�

USING MULTIPLE PAIRS

If you plan to simultaneously use more than one CAM-2W transmitter/receiver pair in the same vicinity, make sure that you purchase sets that rely on slightly different frequencies� They're identied on the model sticker located on the back of the box as G1,

G2, G3, or G4. (See Specications for the two frequencies each version exploits.) Also, the frequencies available per the two channels

on each transmitter and receiver are labeled on the back of each device� Assuming you're using correctly matched units, you can deploy up to four wireless pairs at once�

TROUBLESHOOTING

Radio Frequency (RF) Interference

Radio Frequency (RF) interference is not unusual when dealing with VHF wireless microphone systems. Since the Polsen CAM-2W and CAM-2WC use VHF frequencies to transmit the audio signal, there may be times when it is forced to share the “airspace” with

devices transmitting on similar frequencies� This is a common problem; particularly in urban areas where power lines, cars or car

radios, cell phones, computers, and even garage door openers operating nearby can interfere with frequencies. When experiencing RF interference, you may hear static, white noise bursts, a hum, or a radio signal. If this happens, your CAM-2 system is not malfunctioning. A few simple steps can be taken to eliminate RF interference.

12

Problem Solution

The selected channel

Switch the Channel Selector Switch to the other channel on both the transmitter and receiver�

is noisy

Adjust antenna to 45 degree angle for best reception.

Try using fresh batteries�

If transmission is lost within a room (indicated by noise on the earphone), try changing position�

Overhead telephone lines, uorescent lighting, or close proximity to metal fences can all cause interference.

If this occurs try changing position�

If outdoors, move your location indoors where there may be less interference�

If indoors, change location to another part of the room or building making sure to keep some distance from computer equipment or low-hanging overhead lighting�

Turn off all computers and cell phones�

13

Other Troubleshooting Issues

Problem Solution

No Audio Make sure the Power switch on the transmitter and receiver is set to ON and that the LED indicator is lit�

If LED indicator is not lit, make sure batteries are properly installed (see Battery Installation instructions above)�

Make sure the proper connections have been made (see Recording to HDSLR, Video Camera, or Audio Device section)�

Make sure the Channel Selector Switch on the receiver and transmitter are set to the same channel�

Make sure video camera, HDSLR camera, or audio device is in record mode and the record level is set�

Too much ambience is being picked up

When using an omnidirectional microphone (as provided with the CAM-2W system) the microphone may be picking up too much ambience�

Make sure the microphone is as close to the subject as possible.

If there is still too much ambience, try switching to a cardioid microphone (PL-2WC), as this will record less of the sound from the peripheral area�
