Important Safety Information

Placement

Location & Environment

Do not locate near electronic products that may transmit RF, such as microcomputers, fax machines, TVs
etc, or connect them to the same mains socket as these devices. Also avoid close contact with the mains or
signal leads of such products – careful routing of the cables may be required.
It is better if possible to keep the LP12/Valhalla separate from other products to prevent its operation being
adversely affected by the heat and strong electrical field emitted by some products.
Avoid locations that have high humidity or the chance of the unit getting wet.
Avoid locations where there is a lot of dust.

Handling & general maintenance.

No standard maintenance to the Valhalla is possible or advisable.
Always handle the LP12/Valhalla with great care.
Do not carry out any work with the unit powered up – see Safety Information above.

ALWAYS

 take anti-static precautions when handling the circuit board, as tiny static discharges from your

body that you may be completely unaware of, can damage electronic circuitry and cause major problems.
Anti-static earth mats & wrist straps must be used when handling any of the circuit boards or any spare parts.
