9. Miscellaneous Information
Guidance and Manufacture’s Declaration for Electromagnetic Emissions
The VALO is intended for use in the electromagnetic environment specified below. The customer or user should ensure that it is used in such an environment.
WARNING: Use only authorized accessories, cables, and power supplies to prevent improper operation, increased electromagnetic emissions or decreased electromagnetic
immunity.

Group 1
VALO uses a Globtek medical grade 9VDC adaptor, operates with brown-out protec-
tion, and provides limited EMI, RF, and surge suppression.
VALO uses electrical and electromagnetic energy only for their internal functions.
Therefore, any RF emissions are very low and are not likely to cause interference in
nearby electronic equipment.
The VALO is suitable for use in all establishments, including domestic establishments
and those directly connected to the public low-voltage power supply network that
supplies buildings for domestic use.

Note 2: Self recovers
Mains power quality should be that of a typical residential, commercial,
hospital, or military environment.
The Globtek 9VDC medical grade adaptor that is supplied with the VALO
operates from mains ranging from 100VAC – 240VAC and is capable of limited
brown out, EMI, and surge protection.
If the VALO user requires continued operations without mains interruption,
or the mains in any particular region of a country are considered bad due to
continuous brown-out, black-out, or excessively noisy power conditions, it
is recommended that the VALO be powered from an uninterruptible power
supply or the customer purchase a VALO Cordless unit.

Power frequency magnetic fields should be at levels characteristic of a typical
location in a typical, residential, home health care, commercial, hospital, or
military environment.
NOTE: U is the a.c. mains voltage prior to application of the test level
Note 1: The VALO is not equipped with any ports or any accessible I/O lines.
Note 2: If there is a drop of 95% in Mains voltage VALO will not operate. It has no internal energy storage mechanism. The VALO will turn off. When power levels are restored, VALO
will restart and return to the same state before power loss. The VALO will self-recover.
