Installation / Setup
The installation of the BK 1692 Switching Mode DC Power Supply requires ensuring that the electrical outlet is properly earth-grounded to prevent electric shock. The unit should not be placed in high humidity, dusty areas, or direct sunlight, and should be located where free air circulation is possible. It should not be placed close to TV sets or CRT monitors. The power supply should be connected directly to an AC outlet to avoid heating plugs and cables. It must be placed horizontally for accurate meter readings. The unit is intended for indoor use only.
Operation
The manual provides the following basic usage steps for the BK 1692 Switching Mode DC Power Supply:
1. Ensure the AC power source matches the input voltage of the unit and plug it into the AC outlet.
2. Turn on the unit and adjust the output voltage to match the input voltage of the equipment, then turn off the unit.
3. Connect the equipment to the unit: connect the red (+) to the positive polarity input and black (-) to the negative polarity input of the equipment.
4. Turn on the unit first, then turn on the equipment.
5. When finished, turn off the equipment first, then turn off the unit.

Safety & Warnings
Please read through this operation instruction carefully and follow the instructions to prevent personal injury from misuse or damage to the unit. Please keep this manual for future reference.
SAFETY PRECAUTIONS
1. NEVER remove the metal cover of the power supply while AC power is connected.
2. NEVER touch the unit when your hands are wet.
3. NEVER operate the unit if foreign materials such as metallic objects, water, or other debris have fallen inside. Contact your dealer for repair.
4. NEVER operate a unit that has been damaged, as the voltage regulation circuitry may have been disabled. The resulting high voltage could damage your equipment.
5. NEVER allow foreign objects to touch the DC Power Output Terminals.
6. If you have the need to inspect the interior of the unit, let it cool down completely, as some components may be hot enough to burn your hand in the event of component failure.
7. NEVER block the cooling fan air intake window.
