Battery Installation

The McIntosh MCLK12 Analog Clock uses a long life Lithium Coin Cell type battery. The MCLK12 will function without a battery when connected to AC Power. However, the battery will keep the current time in the event there is an interruption of AC Power and thus prevents the necessity of having to reset the correct time when AC Power is restored. The MCLK12 may be supplied with a battery depending on the country where the MCLK12 is purchased. When purchasing a battery for use in the MCLK12 refer to the following list:

Approved Lithium Batteries

Brand IEC No. ANSI/NEDA No.

Energizer CR2032

Panasonic CR2032(PA/1B)15004LC

5004LC

Access to the recessed battery compartment is located on the Rear Panel of the MCLK12. Refer to figure 1.

Perform the following steps to install the battery:

1. Press the tab and lift up on the Backup Battery Cover and temporarily place it aside. Refer to figure 2.

2. Remove the CR2032 Battery from its packaging.

3. Orient the battery so the + symbol (en-

Battery Installation and Replacement

Battery Removal

The life of the Lithium Battery used in the McIntosh Clock is approximately the shelf life of the battery

(10 - 15 years). However, it is advisable to remove the

battery from the MCLK12 when the clock is not connected to AC Power for an extended period of time. This will help to extend battery life and avoid possible damage to the clock. Perform the following steps to remove the battery from the clock:

1. Disconnect the AC Power Cord from the Rear panel of the McIntosh MCLK12 Clock. Refer to figure 1.

2. Press the tab and lift up on the Backup Battery Cover and temporarily place it aside. Refer to figure 2.

3. Refering to figure 7, use a small pocket size screw driver (or

other suitable tool)

and carefully insert the tip of the tool between the metal tab of the battery socket and the left side of the battery. Then rotate the tool to release the battery from the socket. Remove the battery from inside of the clock.

5. Reinstall the Backup Battery Cover. Refer to figure 6.

6. Store the battery in a cool dry place for future use or dispose of the battery in accordance with the local regulations for lithium battery disposal. Batteries should never be thrown away or incinerated.

General Information

1. For additional connection information, refer to the

owner’s manual(s) for any component(s) connected

to the MCLK12 Analog Clock.

2. The Main AC Power going to the MCLK12 and any other McIntosh Component(s) should not be applied until all the system components are connected together. Failure to do so could result in malfunctioning of some or all of the system’s normal operations. When other McIntosh Components are in their Standby Power Off Mode, the Microprocessor’s Circuitry inside each component is active and communication is occurring between them.

3. When discarding the unit, comply with local rules or regulations. Batteries should never be thrown away or incinerated but disposed of in accordance with the local regulations concerning battery disposal.

Meter Illumination Control Pass Thru

Power Control Connector

The MCLK12 Power Control Input receives an On/ Off signal from +5 to +12 volts. The Power Control Output will in turn provide a +5 to +12 volts Output Signal with a total current up to 50mA. An additional connection is for controlling the illumination of Hours and Minutes Meters on the MCLK12 along with Power Output Meters on compatible McIntosh Power Amplifiers. The 1/8 inch stereo mini phone plug connects to a McIntosh Preamplifier or A/V Control Center Power Control Output.
