IMPORTANT INFORMATION
Electrical shock
Do not open the enclosure, except as instructed to install an upgrade kit. When installing an
upgrade kit, disconnect the power adapter before removing the enclosure cover, and replace the
cover before reconnecting the power adapter.
Do not expose the TalkSwitch to any liquids; that can pose a risk of electrical shock.
Power and lightning surge protection
Surge protection devices are recommended to protect TalkSwitch in areas subject to lightning or
power surges. Please consult your reseller for recommended surge protection devices.
If TalkSwitch has been supplied with surge protection devices to meet local regulatory
requirements, these devices must be installed as described in their installation instructions.
Do not connect or disconnect any telephone lines during thunderstorms.
Power adapter and power cord
Use only the power adapter and power cord supplied with your TalkSwitch. Check the supply
voltage matches the rating on the power adapter label. If your supply voltage does not match
the power adapter rating, please consult your reseller.
For safe operation, the TalkSwitch power adapter must be connected to a power supply socket
with a third pin (ground /earth).
Power failure
The equipment will not operate when mains power fails.
Please ensure a standard telephone that does not require mains power is connected to extension
jack E4 for emergency use. During a power failure telephone line port L1 will connect to
extension jack E4 (except–AU models).
Change password frequently
Setting and frequently changing the system password is recommended to avoid unauthorized
changes to system configuration and settings.
PBX fraud
It is recommended that call bridge (DISA) and call back passwords are changed frequently to
avoid unauthorized users making telephone calls through the TalkSwitch.
Emergency service numbers
Ensure emergency service numbers are not blocked by the toll restriction feature. Frequently
used emergency service numbers are pre-programmed to avoid blocking, but other local numbers
may be used in some locations.
Before routing any emergency service numbers to a VoIP service provider, check that they do
handle emergency service calls and any conditions associated with this service.
