Software Upgrade Procedure
Refer “Updating the software version and
using CNUT” in the PTP 450 Configuration
and User Guide
Resetting to Factory Defaults (2
options)
1. On the radio GUI, navigate to
Configuration, Unit Settings and
select Set to Factory Defaults
OR
2. On the radio GUI, navigate to
Configuration, Unit Settings and
enable and save option Set to Factory
Defaults Upon Default Plug
Detection. When the unit is powered
on with a default/override plug (see
section “Acquiring the Override Plug”
in the PTP 450 Configuration and User
Guide ) the radio is returned to its
factory default settings.

Safety and regulatory information
This section describes important safety and regulatory guidelines that must be
observed by personnel installing or operating PTP 450 equipment.
Important safety information
To prevent loss of life or physical injury, observe the safety guidelines
in this section.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
Grounding and protective earth
PTP 450 units must be properly grounded to protect against lightning. It is the
user’s responsibility to install the equipment in accordance with national
regulations. In the USA, follow Section 810 of the National Electric Code,
ANSI/NFPA No.70-1984 (USA). In Canada, follow Section 54 of the Canadian
Electrical Code . These codes describe correct installation procedures for
grounding the outdoor unit, mast, lead-in wire and discharge unit, size of
grounding conductors and connection requirements for grounding electrodes.
Other regulations may apply in different countries and therefore it is
recommended that installation of the outdoor unit be contracted to a
professional installer.
Powering down before servicing
Always power down and unplug the equipment before servicing.
Primary disconnect device
The BHM or BHS unit’s power supply is the primary disconnect device.
External cables
Safety may be compromised if outdoor rated cables are not used in connections
for those exposed to the outdoor environment.

v
RF exposure near the antenna
Radio frequency (RF) fields are present close to the antenna when the
transmitter is on. Always turn off the power to the PTP 450 unit before
undertaking maintenance activities in front of the antenna.
Minimum separation distances
Install the BHM or BHS so as to provide and maintain the minimum separation
distances from people.
Important regulatory information
The PTP 450 product is certified as an unlicensed device in frequency bands
where it is not allowed to cause interference to licensed services (called primary
users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators
have mandated special requirements to protect these systems from interference
caused by unlicensed devices. Unlicensed devices must detect and avoid co-
channel operation with radar systems.
Installers and users must meet all local regulatory requirements for radar
detection. To meet these requirements, users must set the correct region code
during commissioning of the PTP 450. If this is not done, installers and users
may be liable to civil and criminal penalties.
Contact the Cambium helpdesk if more guidance is required.
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers
to implement special features to prevent interference to radar systems that
operate in the 5250-5350 and 5470-5725 MHz bands. These features must be
implemented in all products able to operate outdoors in the UNII band. The use
of the 5600 –5650 MHz band is prohibited, even with detect-and-avoid
functionality implemented.
Manufacturers must ensure that such radio products cannot be configured to
operate outside of FCC rules; specifically it must not be possible to disable or
modify the radar protection functions that have been demonstrated to the FCC.
In order to comply with these FCC requirements, Cambium supplies variants of
the PTP 450 for operation in the USA or Canada. These variants are only
allowed to operate with region codes that comply with FCC/IC rule.
