2. GENERAL DESCRIPTION

The ER-2230W and ER-2930W are 30 W shoulder-type megaphones featuring a built-in whistle. Designed to house an optional wireless tuner module, the ER-2930W can be used to make announcements from remote locations using a wireless microphone when so equipped.

3. FEATURES

• The microphone attached to the megaphone is equipped with a talk switch and volume control that offer easy operation.

• An optional wired microphone can be connected to the external microphone input to make public address announcements and an audio player to the auxiliary input terminal to play music.

• A 12 V storage battery can be connected to the external power input terminal for extended operation.

• The operation panel's power indicator permits easy checks of the remaining battery voltage level (either continuously lit or flashing)

• Can be mounted on the optional ST-16A speaker stand.

• Microphone with anti-bacteria treatment improve hygiene and safety during use.

• Though not waterproof constructed, the megaphones can be used in locations exposed to light rain or a spray of water with use of the supplied splash-proof cover.

7. USING THE SUPPLIED MICROPHONE

Step 1. Detach the microphone from the microphone hanger.

Step 2. Using the volume control, adjust the volume to an

appropriate level that does not generate feedback when holding down the talk switch.

Feedback is more likely to occur when using the megaphone indoors or in other reverberant places. Particularly when the batteries are new, it may be impossible to adjust the volume to maximum without causing howling. In such cases, set the volume to about mid-level.

Step 3. Speak into the microphone while holding it about 1 cm

away from the mouth. Note: Speaking too far from the microphone or in too

soft voice may result in insufficient volume.

[When Attaching the Microphone]

Reduce the volume to its lowest setting, then press the microphone onto the hanger. Leaving the volume set higher can cause howling if the talk switch is accidentally pressed when attaching or detaching the microphone.

Step 1. Remove the tuner cover located above the battery

cover. To do this, remove both the left and right cover mounting screws.

Step 2. Insert the optional WTU-3800/4800 Wireless Tuner

Module into the tuner receptacle.

Notes

• Avoid using any other than the designated type of tuner module. The megaphone could be damaged.

• Ensure that the group/channel numbers of the tuner module match those of the wireless microphone.

• Take care regarding the correct orientation of the tuner module and fully insert the module into the tuner receptacle.

Step 3. Replace the tuner cover.
