Temperature Mode

The Temperature mode allows you to know the ambient temperature on both the Centigrade and Fahrenheit scales. In addition, you can set high and low tempera- ture limits on either scale; when a limit is reached or exceeded, the unit will sound a warning melody, repeating it every 5 seconds. As an additional feature, the tempera- ture alarm limits can be automatically transmitted on the current channel, together with your user ID; this will occur every 5 minutes when the preset alarm temperature is reached or exceeded, provided the temperature plus transmit mode is enabled (+TX). To access the temperature mode, proceed as follows:

1.From the FRS TWO WAY mode (CH and CODE displayed), press the Function(F) button 4 times; TEMPERATURE is momentarily displayed, followed by the temperature indication (TEMP) in Centigrade or Fahrenheit.

NOTE: When moving from a moderate temperature environment to either a cooler or hotter environment, allow about 20 minutes for the unit temperature sensing element to stabilize.

2.To change the temperature scale, press the right menu button once; C or F will flash.

3.Press the Up button (6); the temperature scale will change from C to F or vice-versa.

To set the high and low temperature alarm limits:

4.Access the temperature mode as outlined in step 1. Press the right menu button again; ON or OFF will appear flashing. Press the Up or Down button (11) to set temperature ON; then press the Monitor (M) button to confirm.

5. With TEMP in C or F displayed, press the right menu button three times; AL H: appears with the temperature indication flashing, provided temperature is ON. The indication will be in F or C, depending on the temperature scale previously selected.

6.Press the Up or Down button to set the high temperature alarm limit; if the low temperature alarm is desired, proceed to step 7. If not, press the Monitor (M) button to confirm the high temperature setting.

7.Press the right menu button; AL L: appears with the C or F indication flashing provided temperature is ON.

8.Press the Up or Down button to set the low temperature alarm limit; then press the Monitor (M) button to confirm the low temperature setting.

The temperature alarm transmit mode will automatically transmit a call tone with the radio’s identification (ID) code (if entered) and temperature to other FR-1500 XTM units on the same channel. This mode is accessed in the following manner:

9.Repeat steps 4 through 8 to set the high and/or low temperature alarm limits; then press the right menu button until ON is flashing.
