The High-Low displays are as follows: Sequence Press [HI/LO] X 1 Press [HI/LO] X 2 Press [HI/LO] X 3 Press [HI/LO] X 4 Respective Display Displays the HIGH temperature Displays the HIGH humidity Displays LOW temperature Displays LOW humidity
3. Repeat steps 1 and 2 to set the maximum humidity setting and the minimum temperature and humidity settings. 4. When finished, press [HI/LO] to set another limit or wait 16seconds and the unit will automatically return to the normal display mode. The appropriate HI, LO or both indicators will be displayed indicating the alarm status. When the alarm activates the main unit LCD screen display will automatically switch to channel-1 if in another remote sensor channel mode and will flash. The alarm will sound for one minute unless disabled. Press any key to momentarily stop the alarm. The alarm will automatically reactivate again if the limit continues to exceed the set limits. NOTE: Temperature Range: The temperature range is from -58F to 158F (-50C to 70C). When setting the limits for the first time, the low/minimum limit will start at -58F (-50C) and the high/maximum limit at 158F (+70C). After the initial setting, the high/low limits will start from the temperatures as last selected. NOTE: Humidity Range: The humidity range is from 2% to 98%. When setting the lim its for the first time, the low/minimum limit will start at 2% and the high/ maximum limit at 98%. After the initial setting, the limits will start from the humidity levels as last selected. NOTE: Alarm Sounding: If a set limit is exceeded a second time while the alarm is sounding, the alarm will complete its first 1-minute cycle before sounding for another 1-minute cycle indicating that a limit has been surpassed a second time. 8

Each press will increase the setting in increments of one (1) degree or humidity percentage. Press and hold [ v ] for rapidscrolling increments of five (5) degrees or humidity percentage.
To turn the alarm off: 1. While the alarm is sounding, press [HI/LO]. 2. Then press [ALARM ON/OFF]. 3. The alarm has now been disabled and will not sound again until reactivated. To temporarily deactivate a sounding alarm: 1. Press any button and the alarm will be temporarily deactivated. The alarm will sound again when a set limit is exceeded.

TRANSMISSION INTERFERENCE
Signals from household devices, such as door bells, home security systems and entry controls, may interfere with those of the RMR-136HG and result in temporarily reception failure. This is normal and will not affect the general performance of the product. The transmission and reception of temperature and humidity data readings will resume once the interference ends. The success of wireless data transmission may vary and is directly related to where the remote sensor is placed and the environmental factors of that location. Should there be difficulty in data transmissions, verify: 1. The low battery warning icon is not displayed for either the main unit or the remote sensor. Replace batteries as necessary. 2. The remote sensor is within the effective transmission range of 21 - 32 yards from the main unit. 3. That there are no obstacle (like a transmission tower) or environmental reason (such as a steep hill) that is causing the interference or blockage between the main unit and the remote sensor. If the difficulty continues, reposition the remote sensor to a different location and/or closer to the main unit.

INTERRUPTED SIGNALS

If the display for a particular remote sensor goes blank on the main unit LCD screen, press [CHANNEL] and [MEMORY] on the main unit at the same time for about 2-seconds to trigger a signal search between the main unit and the remote sensor. If the search does not reactive the signal reception, verify: 1. The remote sensor is still in position. 2. The low battery warning icon is not displayed for the main unit or the remote sensor. Replace batteries as necessary. 3. The remote sensor is within the effective transmission range of 21 to 32 yards from the main unit, and that the transmission path is clear of obstacles and interference. Shorten the distance if necessary. NOTE: When the temperature falls below freezing point, the batteries in the remote sensor will freeze lowering the voltage supply and the effective range.
CALENDAR CLOCK DISPLAY MODES
The RMR136HG has two different time display modes:

MODE 1:

Local Time
Hour, Minute, Second, Month, Day
after 48 hours, remove the batteries, allow the unit to clear and then reinsert the batteries. Once the RMR-136HG receives the initial signal, updates are accomplished with greater ease. IMPORTANT: Do not adjust the time zone until AFTER the clock has picked up the signal. NOTE: SIGNAL STRENGTH

MODE 2:

Hour, Minute, Day-of-the-Week, Month, Day
The RMR-136HG, like other radio frequency equipment, is most effective when it is placed near a window. The RMR-136HG may need to be moved or repositioned to receive a stronger signal. For best reception, place the RMR-136HG away from metal objects and electrical appliances to minimize interference. On the bottom line of the LCD screen immediately to the left of the time display, is an icon indicating the signal reception strength. Please note that while the RMR-136HG is receiving a signal from the US Atomic Clock, the receiving icon will flash; once the signal reception is complete, the icon will stop flashing. Signal Strength Icons:

Press [SET/MODE] switch between the two time display modes. Note: When [24 hr OFF / ((.))] is pressed the bottom line of the main unit LCD screen will display the alarm time.
EXACTSETTM CLOCK SIGNAL RECEPTION
The split-second accuracy of the RMR-136HG is achieved through its internal antenna that responds to a special 60kHz frequency signal generated by the US Atomic Clock. The RMR-136HG automatically activates its antenna upon battery insertion and within 3 - 7 minutes should receive the US Atomic Clock signal. Note that if the RMR-136HG is new allow up to 72 hours for the unit to receive the initializing signal. The strongest signal reception usually occurs between midnight and 4:00 AM. However, if the RMR-136HG has not picked up a signal 10
