[. . . ] Several sets of alternating numbers will be displayed on the cellular handset. The line with six digits displays on the left three digits for the control channel and three digits for the signal strength (Received Signal Strength Indication, RSSI) on the right. To check for proper antenna position, move the antenna and check the readout. [. . . ] Power the unit down from the handset, move SW1 to "Normal", and power the RTS unit up again. AutoSafe Power-up Circuit The RTS-100-N3RH is equipped with a special power-up circuit that will energize the transceiver if power has been accidentally turned off from the Motorola cellular handset, the red/LED switch, or by a power failure. After approximately 30 seconds, the transceiver will power up automatically. The power-up circuit will be disabled if the RTS unit has been shut off by the thermal shutoff protection circuit. This circuit will turn the RTS-100-N3RH off if the temperature is below -40F or above +140F. When the temperature rises to -38F or drops to +138F, the unit will be turned on again. Operating the RTS-100-N3RH from a Battery Use a suitable 12 VDC battery. The red LED/switch and the transceiver will be turned on at the same time. Your RTS-100-N3RH is equipped with a circuit that monitors the battery voltage to prevent sulfurization of the battery. When the battery voltage drops below 10. 8 volts, the cellular transceiver is turned off within approximately 10 seconds. To energize the RTS unit, you must apply at least 85 VAC at the terminal block for AC input. Alternatively, disconnect the discharged battery and connect a fully charged battery at J8. The RTS-100N3RH will power up as soon as power is applied. Page 3 Troubleshooting Installation and Operation of the TransTel RTS-100-N3RH Actions 1.
