Storage environmental conditions
Storage temperature range
-20°C to 65°C (-4 °F to 149°F) with battery
removed.
Storage humidity range
0% to 90% non-condensing
Coupler volume coefficient
No effect until overload occurs.
Electromagnetic emissions and susceptibility
Emission better than CISPR 22, Class/Type B susceptibility better than 10 V/m, 150 kHz to
1GHz. 50/60 Hz magnetic immunity. No effect. 80 A/m
Background acoustic level
Requires greater than 25 dB signal-to-noise ratio, for optimum performance. If external noise
is too high, it may reduce output level.
Power
Battery type
1 x 9v alkaline battery.
(Quest 058-176, ANSI/NEDA 1604A, IEC 6LR61)
Battery life
The battery life will be approximately 18 hours (@ 1kHz) at reference
environmental conditions, mounted on a microphone.
