Product description: -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 operation 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 
 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 shielding effect. Thanks to the enclosure protection rating of IP 54, the digital   selectors can be installed outdoors if required.


Audible signal status:
 -1 short beep-Keypad tone-1 long beep-Modification of combination confirmed (or send the signal after enter the correct password )-5 short beeps-Error during combination input or combination edit operation-2 low beeps-Battery low warning signal New batteries required

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 key3 or 4 to 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 signalwhen the confirom key is pressed 

-The combination entered must be exact,if, for example: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 key3 or 4 should be pressed        immedliately to generate 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: -1a combination to transmit the code associated with the 3 key
 -When the unit is used for the first time this combination is11 -2a combination to transmit the code associated with the 4 key
 -When the unit is used for the first time this combination is 22
