Installing Batteries

Batteries are supplied with the unit. The life of these batteries may be limited, however, since their primary purpose was to enable testing.

Insert the included batteries as shown in figure, being careful to orient the batteries correctly.

ROLAND CE-20 - Installing Batteries - 1

NOTE

  • When turning the unit upside-down, get a bunch of newspapers or magazines, and place them under the four corners or at both ends to prevent damage to the buttons and controls. Also, you should try to orient the unit so no buttons or controls get damaged.
  • When turning the unit upside-down, handle with care to avoid dropping it, or allowing it to fall or tip over.
  • Make sure the "+" and "-" ends of the batteries are oriented correctly.
  • When the batteries run down, the POWER indicator gets dim. If this happens, replace with new batteries.
  • When replacing the batteries, use six AA type.
  • Avoid using new batteries together with used ones. In addition, avoid mixing different types of batteries. Doing so can result in fluid leakage.
  • Battery life can vary depending on battery type.

ROLAND CE-20 - NOTE - 1

Continuous usage time under battery power is about 10 hours with alkaline batteries and about 4 hours with carbon batteries. (This may vary according to usage conditions.)

Making the Connections

NOTE

  • The use of an AC adaptor is recommended as the unit's power consumption is relatively high. Should you prefer to use batteries, please use the alkaline type.
  • Noise may be produced if wireless communications devices, such as cell phones, are operated in the vicinity of this unit. Such noise could occur when receiving or initiating a call, or while conversing. Should you experience such problems, you should relocate such wireless devices so they are at a greater distance from this unit, or switch them off.
  • Use a cable from Roland to make the connection. If using some other make of connection cable, please note the following precautions.

  • Some connection cables contain resistors. Do not use cables that incorporate resistors for connecting to this unit. The use of such cables can cause the sound level to be extremely low, or impossible to hear. For information on cable specifications, contact the manufacturer of the cable.

  • When the unit is running on battery power, the power comes on when you insert the connector plug into the INPUT R (MONO) jack.

  • To prevent malfunction and/or damage to speakers or other devices, always turn down the volume, and turn off the power on all devices before making any connections.
  • If there are batteries in the unit while an AC adaptor is being used, normal operation will continue should the line voltage be interrupted (power blackout or power cord disconnection).
  • Once the connections have been completed, turn on power to your various devices in the order specified. By turning on devices in the wrong order, you risk causing malfunction and/or damage to speakers and other devices.

When powering up: Turn on the power to your guitar amp last.

When powering down: Turn off the power to your guitar amp first.

  • Always make sure to have the volume level turned down before switching on power. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction.
  • When operating on battery power only, the unit's indicator will become dim when battery power gets too low. Replace the battery as soon as possible.
  • Turn on the power before you connect headphones. When turning off the power, first unplug the headphones, then switch off the power.
  • Please observe due caution when using headphones while the LEVEL switch is set to +4 dBu, since their volume may get significantly higher.

Troubleshooting

The power doesn't come on.

Is the guitar connected correctly to the INPUT R (MONO) jack?
Check the connections again (p. 3-9).

  • When running off batteries, the unit won't switch on unless there's something plugged into the INPUT jack. This helps conserve the batteries.

Is the plug connected to the INPUT L jack?
When using battery power, connect the plug to the INPUT R (MONO) jack.
Have the batteries run down?
Replace with fresh batteries (p. 2).
Is the specified AC adaptor (PSA-series sold separately) connected correctly?
Check the connections again (p. 3-9).

There is no sound/volume is too low.

Is the other equipment connected correctly?
Check the connections again (p. 3-9).
Is the volume turned down on the connected guitar/bass amp, effects processor, or other device?
Check the settings on the connected equipment (p. 3-9).
Is the LEVEL switch on the rear panel set correctly?
Set the LEVEL switch to match the connected equipment (p. 3-9).
Is the direct sound ON/OFF set to OFF?
Only the effect sound is output when this is set to OFF. When you want to output the direct sound as well, set this to ON (p. 22).
Is the effect level set to minimum?
Operate the E. LEVEL knob to adjust the effect level.

Sound is distorted.

Are the EFFECT TONE (LOW/HIGH), BRILLIANCE, and AMBIENCE knobs positioned correctly?
Sounds may become distorted with the knobs at certain settings. Turn down one or more of these knobs, or turn down the E. LEVEL knob until the PEAK indicator does not light up too frequently. If in spite of these measures the sound is still distorted, lower the output level of the device connected to the INPUT jacks, or set the LEVEL switch to AMPLIFIER SEND/RETURN (+4 dBu).
Is the LEVEL switch set to GUITAR/BASS?
When connecting to guitar amps, bass amps, or other such gear, or when connecting to equipment that outputs sound at high volumes, set the LEVEL switch to AMPLIFIER SEND/RETURN (+4 dBu).

Pressing the MEMORY/MANUAL pedal does not call up the intended memory.

Is the proper Pedal mode set for your current application?
→ The MANUAL/MEMORY pedal (or the MANUAL/MEMORY pedal when pressed simultaneously with EFFECT ON/OFF pedal) functions differently according to the Pedal mode settings. Use the most appropriate setting for your particular application (p. 11-12).

The volume level of the instrument connected to INPUT jack is too low.

Could you be using a connection cable that contains a resistor?
Use a connection cable that does not contain a resistor.
