This is a dual channel transmitters that are activated only after having entered a Suitable combination.
The units are designed for installation in indoor or outdoor locations. That ensures the utmost security because the transmitted code is changed at each transmission session.
The estimated transmission range is 200 m in open space and 35 m indoors.
The units are designed to ensure battery life equivalent to an estimated 2 years of oper-ation considering 10 transmissions/day.

Installation:
Before physically installing the it in their mouning position it is good practice to perform a practical test to assess their functionality and effective range. Consider that range may be up to 25 or 30% less when battery power is low .
1) positioning
Apart from the distance from the receiver, the units should not be positioned in the vicinity of or-worsestill-in contact with metal structures, which could otherwise exert a signal shieldings effect. Thanks to the enclosure protection rating of IP 54, the digital selectors can be installed outdoors if required.
2)Method of use
The use of the keypad is based on ‘combinations’, i.e. numbers of from 1 to 9 digits that the user is required to key in by means of the keys.Once the combination has been entered the user then presses confirm key3or4to transmit the activation command
to, respectively.
-receiver channel 1 if the user presses3
-receiver channel 2 if the user presses4.
The command will be transmitted only when a valid combination has been entered – if an incorrect combination has been entered the selector will emit an error, warning signal when the confirom key is pressed . The combination entered must be exact,if, for exam-
ple ,the correct combination is 0422, the following attempts will be interpreted as errors:422, 10422, 04222. Therefore, if the user inadvertently presses the wrong key when entering a combination, combination key3or4should be pressed immedliately to gen-
erate the error tone , after which the correct combination can be entered starting from the
beginning again. While entering the combination no more than 6 seconds can be allowed to elapse between keystrokes,after which interval the combination must be re-entered starting from the beginning.
The units are factory programmed with a standard combination to activate channel one and a standar combination for channel two.
The factory set combinations are as follows:
1.combination to transmit the code associated with the 3key. When the unit is used for the first time this combination is 11
2. combination to transmit the code associated with the 4key. When the unit is used for the first time this combination is 22.
