Setting Up

Power Requirements

Although the EZ-20 will run either from an optional AC adaptor or batteries, Yamaha recommends use of an AC adaptor whenever possible. An AC adaptor is more environmen- tally friendly than batteries and does not deplete resources.

■Using an AC Power Adaptor

Use of an AC power adaptor is recom- mended, especially when you use the EZ-20 for a long period of time.

1Make sure that the [STANDBY/ON] switch of the EZ-20 is set to

STANDBY.

2Connect one end of the adaptor to the DC IN 12V jack on the rear panel of your EZ-20.

3Connect the other end to a suitable electrical outlet.

WARNING

Use ONLY a Yamaha PA-3B AC Power Adap- tor (or other adaptor specifically recommended by Yamaha) to power your instrument from the AC mains.

The use of other adaptors may result in irrepa- rable damage to both the adaptor and the EZ- 20.

CAUTION

Unplug the AC Power Adaptor when not using the EZ-20, or during electrical storms.

■Using Batteries

1Turn the instrument upside-down and remove the battery compartment lid.

2Insert six 1.5-volt “D” size, R20P (LR20) or equivalent batteries as shown in the illustration, making sure that the positive and negative termi- nals are properly aligned.

3Replace the lid.

When the batteries run low and the battery voltage drops below a cer- tain level, the EZ-20 may not sound or function properly. As soon as this happens, replace them with a com- plete set of six new batteries, heeding the cautions described below.

CAUTION

•Insert the batteries in the correct direction, making sure that the positive and negative ter- minals of the batteries match the label. If the orientation does not match the label, the bat- teries may generate heat, cause a fire, or leak.

•Never mix old and new batteries or different types of batteries (e.g., alkaline and manganese).

•To prevent possible damage from battery leakage, remove the batteries from the instru- ment if it is not to be used for a long time.

•Even when the switch is in the “STANDBY” position, electricity is still flowing to the instrument at the minimum level.

When you plan not to use the EZ-20 for a long period of time, make sure you unplug the AC power adaptor from the wall AC outlet, and/ or remove the batteries from the instrument.
