USER'S MANUAL
INTRODUCTION
Thank you for purchasing the RMR-166 Multi-Channel IndoorOutdoor Thermometer with 433MHz Cable Free
sensor and Radio Controlled
™
calendar clock.
This basic package consists of the main temperature and calendar
clock unit and a wireless remote temperature sensor, model THN-
138. The main unit can support up to three Cable Free
sensors. Additional remote sensors are available.
The main unit has a large easy-read LCD screen that displays the
indoor temperature, clock with calendar and temperature data
transmitted by the remote sensor to the main unit. In addition, the
RMR-166 will store in memory the maximum and minimum
indoor temperatures and temperatures transmitted from the remote
sensor.
The RMR-166 clock is a radio-controlled clock. The clock
automatically synchronizes current time and date with radio signals
received from the US Atomic Clock, one of the world’s most
accurate timepieces. To learn more about the US Atomic Clock
visit the US Department of Commerce's National Institute of Standards and Technology website at www.nist.gov. Other features
include three-language display choice, four-step crescendo daily
alarm and easy-change display modes.
