3. INSTALLATION Follow the procedure below to install the TM-2655/TM-2655P. 1. To ensure that the TM-2655/TM-2655P works properly, install the device in an environment where: The temperature range is from 10°C to 40°C (50°F to 104°F). The humidity is less than 85% (non condensing). It is away from water, dust, chemicals, and corrosive or explosive gases. It is not exposed to direct sunlight. 2. Place the TM-2655/TM-2655P on a table solid enough to support its weight. 3.
4. OPERATION 1. Turn on the POWER switch located on the rear panel. When the POWER switch is turned on, all of the display symbols will appear for several seconds. Then; (TM-2655) “0” (zero) appears in the SYSTOLIC pressure display, indicating that the device is ready for measurement. (TM-2655P) The human sensor functions for three minutes. When it does not detect a person, “ . “ (dot) appears in the SYSTOLIC pressure display, indicating that the device is ready for measurement. Fig.
8. When the measurement is complete, the air is automatically released from the cuff and the cuff will become loose. 9. The measurement results appear in the display. 10. (TM-2655P) The measurement results are output to the printer. Fig.9 Measurement results Note z To stop the measurement at any time, press the START/STOP switch. The quick exhaust will reduce the pressure in the cuff and the cuff will become loose.
5. SETTING THE CLOCK 5-1 Clock Adjustment Mode The clock is set in the clock adjustment mode. The clock adjustment mode display and switches used are as shown below: Fig.10 Switches for setting the clock and the clock adjustment mode display Table 3 Switches for setting the clock SELECT switch (1) Press to enter the clock adjustment mode.
