OPERATING INSTRUCTIONS

1. SAFETY PRECAUTIONS

• Be sure to read the instructions in this section

carefully before use.

• Make sure to observe the instructions in this

manual as the conventions of safety symbols and

messages regarded as very important precautions

are included.

• We also recommend you keep this instruction

manual handy for future reference.

• To prevent the electromagnetic wave from badly

influencing medical equipment, make sure to

switch off the unit's power when placing it in close

proximity to the medical equipment.

• When the unit is not in use for 10 days or more, be

sure to take the battery out of the unit because

battery leakage may cause personal injury or

contamination of environment.

2. GENERAL DESCRIPTION

The wireless microphone WM-3310 is of lavalier

type, while the WM-3310H is of headset type, and all

are designed for use on VHF band.

The WM-3310/-3310H accommodate the supplied

microphone unit or headset with a cardioid pick-up

pattern and are suitable for speech reinforcement

applications. The built-in circuitry is so designed to

minimize the influence from ambient noise.

3. FEATURES

• One frequency can be selected from 6 operating

frequencies of 169 – 216 MHz.

• An optimized PLL-synthesizer minimizes the

oscillation frequency drift resulting from the

ambient temperature or voltage fluctuation.

• Audio level control adjusts the microphone

sensitivity.

• Battery lamp indicates battery consumption to

prevent the unit from malfunctioning when the

battery level remarkably decreases.

• Compact size and high reliability

4. HANDLING PRECAUTIONS

• Do not expose the unit to rain or an environment

where it may be splashed by water or other liquids,

as doing so may result in unit failure.

• Never open nor remove the unit case to modify the

unit. Refer all servicing to your nearest TOA dealer.

• Take care not to drop the unit onto the floor nor

bump it against a hard object as the unit could fail.

• Do not place the unit in locations of high

temperature (ex. in a car parked in summer) or

high humidity as the unit could fail.

• Do not use the unit in locations where it is exposed

to seawater.

• To clean, use a dry cloth. When the unit gets very

dirty, wipe lightly with a cloth damped in a dilute

neutral cleanser, then wipe with a dry cloth. Never

use benzine, thinner, or chemically-treated

cleaning towel.

• Avoid using a mobile telephone near the wireless

microphone in use. Noise could be picked up.

WARNING

Indicates a potentially hazardous situation which,

if mishandled, could result in death or serious

personal injury.

CAUTION

Indicates a potentially hazardous situation which,

if mishandled, could result in moderate or minor

personal injury, and/or property damage.
