Safety Information
WARNING: Read the safety information fully before using the aspida.
High volume audible alarm
The aspida employs high volume warning alarms with a sound pressure level of 95dB in the case of
normal gas alarms, and up to 110dB in the case of the man-down alarm. Care should be taken
particularly when the man-down feature is enabled to minimise exposure to the sounder. The aspida
unit should always be worn away from the head in order to minimise close range exposure to the
alarm.
WARNING: The 110dB man-down alarm can be manually activated at any time by holding the
button. Care should be taken not to activate this alarm when the aspida unit is in close
proximity to the ears.
Electrochemical oxygen sensor
The oxygen sensor used in certain aspida options is an electrochemical sensor which contains toxic
compounds. Under normal conditions the sensor will be safely sealed. To prevent leakage, the unit
must not be exposed to temperatures outside the specified range, or be exposed to organic vapours,
which may cause physical damage to the body of the sensor. The unit must not be stored in areas
containing organic solvents or in flammable liquid stores.
WARNING: Read the safety information fully before using the aspida.
Sensor faults
If the unit indicates a fault the user is no longer protected and should evacuate from areas used to
store CO2

About the Product
The Analox aspida is a portable, personal, gas detection instrument capable of detecting potentially
dangerous ambient levels of oxygen and carbon dioxide for protection of people working in confined
spaces. The instrument gives clear audible, visible and vibration warning of potentially dangerous gas
levels. A high resolution Organic Light-Emitting Diode (OLED) display shows clear, live gas level
readings in all light conditions.
The Analox aspida is housed in a robust, IP65 splash proof enclosure and is designed to attach
securely and comfortably to clothing. The instrument operates using rechargeable battery technology,
allowing it to run for more than 12 hours continuously between charges. The Analox aspida allows
for easy replacement of the rechargeable batteries with standard, AA, non-rechargeable batteries in
circumstances where recharging is not possible.
As an additional safety feature, the Analox aspida provides an optional man-down/panic alarm
feature, designed to give a lone-worker peace of mind when working in enclosed areas. When
enabled with this feature, the aspida monitors the user’s movements and sounds an ultra-loud siren
if they should become incapacitated. In addition, a user-activated panic feature can initiate the ultra-
loud siren to signal for help.
Additional feature of the Analox aspida include time-weighted average monitoring of carbon dioxide
levels, multiple user registration for shared devices and a continuous 7 day internal data log. All
features are fully configurable through USB using the Analox aspida Intelligent Configuration
Software.
Sensor Options Available
The Analox aspida is available in three sensor configurations:
a) Carbon dioxide –single sensor
b) Oxygen –single sensor
c) Carbon dioxide and oxygen - dual sensor

Installation of the Product
Before using the Analox aspida, batteries should be inserted into the instrument. If using the
rechargeable batteries provided, it should be given a full charge cycle. A full charge cycle will be
complete within approximately 4.5 hours.
Battery installation
The Analox aspida is powered by a pair of standard AA batteries. The device can be powered using
the NiMH re-chargeable batteries included in the product package or using a pair of standard Alkaline,
non-rechargeable batteries.
To gain access to the battery compartment, undo the screw in the centre of the battery cover on the
rear of the device and lift the cover off. Before removing batteries from the device, ensure that it is
switched off and that the mains charger and USB cable are disconnected.

Charging the Analox aspida
WARNING: The following safety warnings should be observed before attempting to charge
the Analox aspida:
The Analox aspida should only be charged when the NiMH batteries supplied with the
product are fitted. Attempting to recharge non-rechargeable alkaline batteries will in most
cases result in an aborted charge, and this will be indicated by a flashing icon on the
display. However, connecting the mains charger whilst using alkaline batteries is not
recommended and may result in damage to the device.
The Analox aspida may be used with standard rechargeable AA batteries which have been
charged using a third-party charging device. However, only NiMH batteries provided by
Analox should be used when attempting to charge batteries within the device using the mains
charger.
Do not attempt to charge the device using a mains charger other than the one supplied with
the device. Use of an incorrect mains charger may damage the device.
The battery cover should always be securely fitted before performing a charge.
With the mains charger disconnected from the wall outlet, insert the power jack into the socket
on the rear of the aspida device.
Insert the mains charger into the wall outlet.
Switch on the mains outlet.
NOTE: The unit can be charged whilst switched on or switched off.
The following lists the conditions that may be observed during a charge.

to the device then the user-name selection screen will be shown instead. See the section ‘User
registration’for further instructions.
On start-up, the sensors have a short warm-up period. Live gas values will not be displayed until the
sensors have completed their warm-up. For oxygen, the warm-up takes 15 seconds. For carbon
dioxide, the warm-up takes 30 seconds. Sensor warm-up will be shown on the display.
To switch off the device, press and hold the button until the screen goes blank then release the
button.
User registration
The Analox aspida allows for registration of up to two usernames. This allows multiple users to
share use of the device. On start-up, a username is selected, and all subsequent gas information is
logged internally against the selected user ID. Users can be registered to a device using the aspida
configuration software. See the aspida configuration software for instructions.
On device power up, if a single user is registered, the username will be displayed for a few seconds,
after which the device will operate normally.
If 2 users are registered, both usernames will be displayed in a menu for the user to select. Pressing
the button will cycle between highlighted usernames. The button will select the highlighted
user.
NOTE: If a user is not selected within 2 minutes of start-up, a ‘no user’ ID will be selected
automatically and the device will continue to run normally. During this time, a reminder beep will be
sounded to prompt the user to select an ID.

If the user does not operate any buttons for one minute, the screen-saver will activate showing a logo
which will drift around the display with the screen dimmed. Pressing any button will wake the device
from screen saver mode and display the main gas screen. If the device is connected to the charger or
to a PC via USB, the screen-saver will not activate but the screen will still dim as normal.
NOTE: The screen-saver function is intended to extend the battery life and prevent screen burn-in.
During screen saver mode, gas values are still monitored as normal. Any gas alarm will wake the
display from screen saver immediately and the main gas display will be shown.
Battery status
The battery status icon is shown in the top right hand corner of the display. This icon gives a
representative indication of the power remaining in the batteries. As the batteries run down from full to
empty, the battery icon will be displayed in various states.

Battery near empty. Approx. 1 hour of operation remaining.
A reminder beep will sound periodically.
The device is powered from the mains charger. The icon
will be shown next to the battery icon.
The device is attached to and powered by a computer via
a USB cable. The USB symbol will be shown instead of
the battery icon.
NOTE: Due to the nature of the battery type, the battery status icon may temporarily indicate a
capacity higher than the true remaining battery capacity upon switch-on. This effect is usually seen in
devices which have been switched off for an extended period of time. The true battery status will be
indicated within a few minutes of power-up.
