Ergonomic nDesigned for comfortable shoulder placement. Operate inneither hand, clip onto the belt, or use hands-free.
Rugged & Weather Resistant nIP67 is water and dust resistant. Tough enough to withstandnthe working environment.
LCD nImmediate access to caller ID and memories, measurementnof on-hook voltage, off-hook current, and ringing frequency.
DTMF Digit Recognition nEnsures auto-dialing to the correct number. DTMF power isnindicated in dBm to ensure that line conditions are good.
DSL Filter nHigh impedance design ensures maximum digital linencompatibility in both monitor and talk modes.
DigAlert™nDetect and protect digital services and warns the user andnprotects itself from high voltages and currents.
SmartIntercom™nAllows alerting over a “dead” pair of wires. When a call isnrequested from one unit, the other unit wakes up, validatesnthe request, and acknowledges it with a unique tone.
Intercom nTalk over a “dead” pair of wires.
Toner nA built-in pair tracing toner is provided. The frequenciesnchosen are optimized for use with Tempo probes, or anynother probe that works in the telephone audio frequencynrange.
Handsfree & Loudspeaker Convenient duplex speaker phone function plus loudspeaker monitoring.
Photo-Luminescent Keymat Advanced silicone rubber keypad glows after exposure to light, aiding operation in low light conditions.
Warranty Three-year Nautilus™ family limited warranty.
