IntroductionThankyouforpurchasingtheUT52A/MDL,UT32A/MDLController.The UT52A-00B-11-00/x/MDL and UT32A-00B-11-00/x/MDL controllers can only be used in the US.The UT32A-00C-11-00/x/MDL controller can only be used in the Republic of Korea.This operation guide describes the installing, wirings, and setup flow related to the wireless communicaiton function of the UT52A/MDL and UT32A/MDL. For configuring the 920 MHz wireless communication and descriptions not covered in this manual, see the 920 MHz Wireless Communication User’s Manual (IM 04L51B01-41EN), provided as an electronic manual.The guide should be provided to the end user of this product. Be sure to read this operation guide before using the product in order to ensure correct operation.Beforeusingtheproduct,refertothetableofModelandSuffixCodestomakesurethatthedeliveredproductisconsistentwiththemodelandsuffixcodesyouordered.Also make sure that the following items are included in the package.

1. Safety PrecautionsThe following symbol is used on the instrument. It indicates the possibility of damage to the instrument,andsignifies that theusermust refer to theoperationguideoruser’s manual for special instructions. The same symbol is used in the operation guide and user’s manual on pages that the user needs to refer to, together with the term “WARNING”or“CAUTION.”

WARNING

Calls attention to actions or conditions that could cause serious or fatal injury to the user, and indicates precautions that should be taken to prevent such occurrences.

CAUTION

Calls attention to actions or conditions that could cause injury to the user or damage to the instrument or property and indicates precautions that should be taken to prevent such occurrences.

Sleeve antennaSleeve antennas (not waterproof) are used indoors or inside a case. Sleeve antennas do not have directivity. They can also be bent and rotated to change the antenna direction. As such, they can be used anywhere indoors.While turning the antenna to the right, attach the antenna to the antenna connection port.
