Power and Power Management
Powered by a commonly available 9-volt alkaline battery and internally regulated to 5 volts for consistent performance throughout the life of the battery. Audience response system wireless keypad is using power only when transmitting an entered response.
Battery provides sufficient power for 10,000+ responses before requiring replacement.
User Identification
Each keypad has a unique address between 1 and 50 and a radio frequency (RF) channel number. Combining this “address” feature with a special response verification routine provides additional security. Keypads operate independently of each other and keypad addresses are programmable.
Individual pads can be password-protected to preserve configurations.
RF Technology
Proprietary radio communication system provides reliable, barrier free operation between keypads and their associated OptionFinder EZ Group Response Base Station. Integrated error-checking ensures accurate communication of responses.
The keypad design uses license-free frequencies for communicating key presses to the Base Station. A 345 MHz RF keypad transmitter sends keypress information to the Base Station’s receiver. This transmitter is frequency-synthesized and frequency-modulated. Multiple channels provide installation flexibility. Internal antenna is enclosed and protected by the keypad housing.
