The Motorola Mobile Keypad Microphone, identified by kit numbers HMN4079_, HMN4108_, HMN4109_, HMN4110_, and HMN4111_, is a full keypad handheld microphone designed for use with a parent device. This device complies with part 15 of the FCC Rules, ensuring that its operation does not cause harmful interference and that it accepts any received interference.

Function Description

The primary function of the Mobile Keypad Microphone is to facilitate communication and navigation within the menus of its associated parent device. It features a comprehensive keypad that allows users to enter information such as phone numbers and select menu options. The microphone is equipped with a Push-to-Talk (PTT) switch, which must be pressed before speaking to activate the microphone.

Usage Features

The microphone is designed for ease of use and integrates several features to enhance its functionality:

• Keypad: A full keypad is provided for data entry and menu navigation.
• Navigation Keys: Dedicated navigation keys (up, down, left, right) are included to move through menus.
• Data Key: A specific data key is available for data-related functions.
• Home Key: A home key allows users to quickly return to the main screen or a predefined home function.
• Cancel Key: A cancel key is present to exit menus or cancel operations.

• Optimal Speaking Distance: For clear communication, users should position the microphone approximately one inch away from their mouth and speak in a normal voice.

Installation

The installation process for the Mobile Keypad Microphone is straightforward:

1. Hang-up Clip Attachment: The hang-up clip (1) is attached to the vehicle using two sheet metal screws and a back-up plate (4). The back-up plate is placed behind the dashboard. A flat-head screw (2) is used in the top mounting hole, and a hex-washer screw (3) is used in the bottom mounting hole, ensuring that the screws fasten securely into the holes in the back-up plate.
2. Microphone Insertion: The button on the rear housing of the microphone is inserted into the hang-up clip.
3. GCAI Plug Connection: The GCAI plug on the radio end of the microphone cord is inserted into the GCAI jack located on the front of the radio.
4. Securing the Cord: The locking collar on the radio end of the microphone cord is turned 1/4 turn clockwise to secure it in place.

Disconnection

To disconnect the microphone from the radio:

1. Unlocking the Collar: Turn the locking collar on the radio end of the microphone cord 1/4 turn counter-clockwise.
2. Releasing the Cable: Pull the cable from the GCAI connector to release it.

Maintenance Features

Troubleshooting and maintenance for the Mobile Keypad Microphone primarily involve identifying and replacing faulty components, as the individual parts are not designed for repair.

• Troubleshooting Inoperability: If the microphone is inoperable, the issue is typically attributed to either a faulty microphone cord or a faulty microphone head.
• Component Replacement: To diagnose and correct the fault, users are advised to first replace the microphone cord with a spare. If this does not restore operation, the microphone head should then be replaced.
• Non-Repairable Items: Both the microphone cord and the microphone head are considered non-repairable items. Once determined to be faulty, they must be replaced.

Replacing the Microphone Cord

The process for replacing the microphone cord involves removing the old cord and installing a new one:

Removing Cord from Mic Body:

2. Disconnecting TELCO Connector: Disconnect the cord from the microphone body by pulling the TELCO connector (which lacks a tab) out of the TELCO jack on the circuit board inside the microphone body.

Installing Cord Into Mic Body:

1. Sliding Locking Collar: Slide the locking collar on the microphone end of the cord away from the TELCO plug and past the strain relief.
2. Orienting TELCO Plug: Orient the TELCO plug on the microphone end of the cord so that it aligns with the TELCO jack inside the microphone body, with its contacts facing the rear of the microphone housing.
3. Plugging into TELCO Jack: Pass the TELCO plug through the hole at the bottom of the microphone body and plug it into the TELCO jack on the circuit board inside the microphone body.
4. Positioning Locking Collar: Slide the locking collar back up on the cord, ensuring that the tabs on its sides face the sides of the microphone body.
5. Securing Locking Collar: Push the locking collar firmly into the hole at the bottom of the microphone body, then turn it 1/4 turn clockwise to secure it in place.
