Cautions on Handling
- Before turning the power switch on
Check once again that all connections are correct and that there are no problems with the connection cables.
- Power is supplied to some of the circuitry even when the unit is set to the standby mode. When traveling or leaving home for long periods of time, be sure to unplug the power cord from the power outlet.
- Sufficiently ventilate the place of installation
If the unit is left in a room full of the smoke from cigarettes, etc., for long periods of time, the surface of the optical pickup could get dirty, in which case it will not be able to read the signals properly.
- About condensation
If there is a major difference in temperature between the inside of the unit and the surroundings, condensation (dew) may form on the operating parts inside the unit, causing the unit not to operate properly.
If this happens, let the unit sit for an hour or two with the power turned off and wait until there is little difference in temperature before using the unit.
- Cautions on using mobile phones
Using a mobile phone near this unit may result in noise. If so, move the mobile phone away from this unit when it is in use.
- Moving the unit
Turn off the power and unplug the power cord from the power outlet.
Next, disconnect the connection cables to other system units before moving the unit.
- Note that the illustrations in these instructions may differ from the actual unit for explanation purposes.
Cautions on Installation
Note:
For proper heat dispersal, do not install this unit in a confined space, such as a bookcase or similar enclosure.

Discs
Discs Usable on the RCD-M37
Music CDs
Discs marked with the logotype below can be played in this unit.
CD-R/CD-RW

NOTE
- Discs with special shapes (heart-shaped discs, octagonal discs, etc.) cannot be played. Do not attempt to play them, as doing so can damage the product.
- Some discs and some recording formats may not be playable.
Non-finalized discs cannot be played.

- Place the discs flatly, 12cm discs in the outer tray guide (Figure 1), 8 cm discs in the inner tray guide (Figure 2).

Figure 1
Outer tray guide

Figure 2
Inner tray guide
- Place 8 cm discs in the inner tray guide without using an adapter.

- "00 Tr 00 : 00" is displayed if a disc that cannot be played is loaded.
- "00Tr 00:00" is displayed if the disc is loaded upside-down or if no disc is loaded.
NOTE
Do not push the disc tray in by hand when the power is turned off. Doing so could damage the set.
Cautions on Loading Discs
- Only load one disc at a time. Loading two or more discs can damage the unit or scratch the discs.
- Do not use cracked or warped discs or discs that have been repaired with adhesive, etc.
- Do not use discs on which the sticky part of cellophane tape or labels is exposed or on which there are traces of where labels have been removed. Such discs can get caught inside the player and damage it.
Cautions on Handling
- Do not get fingerprints, oil or dirt on discs.
- Take special care not to scratch discs when removing them from their cases.
- Do not bend or heat discs.
- Do not enlarge the hole at the center.
- Do not write on the labeled (printed) surface with ball-point pens, pencils, etc., or stick new labels on discs.
- Water droplets may form on discs if they are moved suddenly from a cold place (outdoors for example) to a warm place, but do not try to dry them off using a hairdryer, etc.
Cautions on Storing Discs
- Be sure to remove discs after using them.
- Be sure to store discs in their cases to protect them from dust, scratches, warping, etc.
-
Do not store discs in the following places:
-
Places exposed to direct sunlight for long periods of time
- Dusty or humid places
- Places exposed to heat from heating appliances, etc.
Cleaning Discs
- If there are fingerprints or dirt on discs, wipe them off before using the disc. Fingerprints and dirt can impair sound quality and cause interruptions in playback.
- Use a commercially available disc cleaning set or a soft cloth to clean discs.

Gently wipe the disc from the inside towards the outside.
Do not wipe with a circular motion.
NOTE
Do not use record spray, antistatic agents, or benzene, thinner or other solvents.

Connections
Connections for all compatible audio signal formats are described in this owner's manual. Please select the types of connections suited for the equipment you are connecting.
With some types of connections, certain settings must be made on the RCD-M37. For details, refer to the instructions for the respective connection items below.
NOTE
- Do not plug in the power cord until all connections have been completed.
- When making connections, also refer to the owner's manual of the other components.
- Be sure to connect the left and right channels properly (left with left, right with right).
- Do not bundle power supply cords together with connection cables. Doing so can result in humming or noise.

Using the AM Loop Antenna
To use suspended on a wall
Suspend directly on the wall without assembling.
Nail, tack, etc.

To use standing alone
Use the procedure below to assemble.

Assembling the AM Loop Antenna
1 Bend in the direction of the arrow.

2 Insert into the hole.

Speaker Connections

Connecting the Speaker Cables
Check the left (L) and right (R) channels and the + (red) and - (black) terminals on the set and the speakers to be used and interconnect the cables to the same polarities.

2 Turn the speaker terminal counterclockwise to loosen it.
3 Insert the speaker cable's core wire into the base of the speaker terminal.
4 Turn the speaker terminal counterclockwise to tighten it.
NOTE
- Use speakers with an impedance of 6 to 16 Ω/ohms. The protection circuit may be activated if speakers with an impedance other than specified are used.
- Connect the speaker cables in a way that they do not stick out of the speaker terminals. The protection circuit may be activated if the core wires touch the rear panel or screws or if the + and - sides touch.
- Never touch the speaker terminals while the power is on. Doing so could cause electric shock.
Protector circuit
The protection circuit will be activated in the following cases:
- When the speaker cable's core wires are touching the rear panel or screws or when the speaker cable's + and - sides are touching
- When the surrounding temperature is extremely high
- When the internal temperature rises due to extended use with a high output
If this happens, unplug the power cord, then check the connections of the speaker cables and input cables. If the set's temperature is extremely high, wait for it to cool off and improve surrounding ventilation. After doing this, plug the power cord back in.
If the protection circuit is activated though there are no problems in ventilation around the set or in connections, the set could be damaged. Turn off the power, then contact a DENON servicing and inquiry outlet.
Connecting the Playback Components
Control Dock for iPod
Use a DENON Control Dock for iPod (ASD-1R or ASD-3N/3W, sold separately) to connect the set with an iPod.


- When using a Control Dock for iPod, the Control Dock for iPod must be set. For details, refer to the operating instructions of the Control Dock for iPod.
To use an iPod, see "iPod® Playback" (page 22).
