WARNING [W222]
▲ Temp Control 1
(v4.1/v4.11)
Probe Discontinuation - temperature
measured is 5°C above set temp for
more than 5 seconds
1. Keep probe(s) inserted at tissue
site until PMG reads a minimum
temperature of 30°C prior to
procedure start
2. Swap out probe and cable as
appropriate
3. Try new probe(s) and cable(s)
4. Press the PMG Output ON/Off
button to turn off/ignore warning
5. Contact HYH Technical Support
if problem persists (844-425-9273)
option 1 then option 3

11 Technical Specifications
11.1 RF Output
› RF energy: 460.8 kHz ± 1 %, Quasi-sinusoidal
› Maximum power: 50 W (available into an impedance range of 60 ohms - 520 ohms,
resistive.) Outside this range, the Generator reduces available power to comply with
specified voltage and current limits.
› Applied part of patient circuit is not referenced to earth at high frequency.
› The maximum output of 50 W is restricted by:
• Maximum voltage: 160 Vrms
• Maximum current: 0.9 Arms
• Maximum peak voltage: 254 V (under normal operating conditions)
• Power output is available into loads of 25 ohms - 3000 ohms
• 100 ohms is the nominal “rated” load.
11.2 Mechanical Specifications
› Size: 9.5 x 12.5 x 14.0” (24 x 32 x 35 cm) maximum
› Weight: 21.0 lb (9.5 kg) maximum (not including power cord or shipping box)
› Moisture protection rating: IPX0 (ordinary, per IEC601)
11.3 Environmental Specifications
› Operational temperature: 10°C to 35°C
› Storage & Transportation temperature: -40°C to 70°C
› Operation, Storage & Transportation Humidity: 20% to 95% non-condensing
Note: For additional details on Technical Specifications including IEC Electrical Safety please refer to
