Notes about the Battery Pack
uGeneral Battery Characteristics
•The battery is a consumable and its performance over time will gradually decrease.
•While not in use, the battery will slowly discharge itself.
Prepare a battery pack that has been charged relatively recently (1 to 2 days earlier).
•To ensure that the battery lasts for a long time, we recommend that you turn off the printer
whenever possible.
• When used at low temperatures, battery performance will temporarily decline. Be sure to have a
fully-charged spare battery standing by if the printer will operate in a cold environment.
uCharging the Battery Pack
• The battery pack can be charged at ambient temperatures between 0 and 40°C.
• The time required to charge the battery pack varies depending on the voltage and the ambient
temperature.
Normally, it takes 4 to 5 hours to charge the battery pack.
• Turn off the printer power while the printer is charging.
• Printing while the printer is charging will shorten the battery lifetime.
• Do not remove the battery pack while it is being charged.
• Fully charge the battery prior to using the printer. Otherwise, the performance of the battery
may be affected.
• There is no need to completely discharge or use up a rechargeable lithium ion battery before re-
charging it.
• It is normal for the battery pack to be hot after it has finished charging or been used.
• Do not frequently repeat charging when there is still sufficient remaining battery charge.
Note: When the battery charger is connected to the printer without the battery pack, the
printer turns on but cannot print.

- 15 -
uBattery Pack Life
• The battery can be charged approximately 300 times in the normal temperature range without
losing performance. If an extreme decline in the running time of the battery is noticed, the bat-
tery is reaching the end of its usable life. It is recommended to replace the old battery with a
new one.
uNotes about Using the Battery Pack
• Only use a designated battery pack. There is a risk of explosion or fire.
• Only use the designated battery charging method. There is a risk of explosion or fire.
(You cannot use a battery charger other than the designated battery charger.)
• Do not throw the battery pack into a fire, place it near a flame or heating device, or use, charge
or leave it in a hot environment (under direct sunlight, in a car, etc.). There is a risk of heat gener-
ation, smoke emission, explosion, fire, or battery acid leakage.
• Do not use a battery pack that has been dropped or subjected to a shock in some other way.
There is a risk of heat generation, smoke emission, explosion, fire, or battery acid leakage.
• Do not disassemble or modify the battery pack.
Doing so could lead to injury, fire, or electric shock.
• Do not short the terminals of the battery pack or get it wet.
Do not put the battery pack in a bag with a metal object such as a key. There is a risk of heat
generation, smoke emission, explosion, fire, or battery acid leakage.
• If the battery acid gets into contact with the eyes, wash eyes immediately with water and consult
a doctor. Leaving your eyes untreated could result in blindness.
• If there is an abnormality such as heat generation, smoke emission, explosion, fire, or battery
acid leakage while the battery pack is being used or stored, remove the battery pack from the
printer immediately. Consult your dealer.
uNotes about Storing the Battery Pack
• The characteristics of the battery pack may degrade if you store it in a charged state for a long
period of time. If you do not intend to use the battery pack for a while, charge it to approximate-
ly 50 %, and then remove it from the printer.
• If you do not intend to use the battery pack for a long time, be sure to remove it from the printer,
and do not leave it connected to a battery pack holder for external charging.
• Keep the battery pack out of the reach of children. In addition, be careful that children do not
remove the battery pack.
• Store the battery pack in a cool place.
* We recommend that you store the battery pack in a dry area with an ambient temperature of
15 to 25 oC.
* Avoid storing the battery in locations with high or extremely low temperatures.

2.2 Bluetooth
2.2.1 Pairing
1. Press and hold POWER button for approx. 5 seconds, and printer is turned on.
Then, it is ready to pair with another Bluetooth device.
3. If necessary, enter the following information into the terminal that you are using.
PIN: 1234 (default)
Device name: Star Micronics (default)
2. On the host device, tap [Settings]. Set [Bluetooth] to ON.
Select "Star Micronics".
CAUTION
1) For security purposes, we recommend that you change the PIN.
The following utility is required to change the PIN.
Please download and use the utility soft from the following URL.
iOS https://www.star-m.jp/prjump/000003.html
Android https://www.star-m.jp/prjump/000004.html
Windows https://www.starmicronics.com/support/
Or, please contact the seller.
For instructions on how to use this utility, please refer to the Bluetooth Setting Utility Software
Manual.
2) If the quantity of data which is printed at once is more than 1M byte on Bluetooth communication,
it would cause the buer to overow and the data to get damaged.
3) For instructions on how to connect with a host device, please refer to your host device user
manual.
<iOS ><Android >
You can test the connectivity with a host device by using StarIO SDK Application which is
available on Apple Store and Google play.

2.2.2 Auto Connection Function (only for iOS*1)
When the Bluetooth connection with your iOS device*2 is disconnected, it is required to establish a
connection by tapping the printer you want to use on the Bluetooth setting screen. This Re Connection
Specication is exactly based on the iOS specications, and this specication is dierent from other OS
such as Android.
The auto connection eliminates this conguration process and automatically sends a request for
connection to the iOS terminal (Host) that the printer previously connected.
See the table below for details of Auto Connection setting.
Auto Connection OFF Auto Connection ON
(Defalt)
How to re-connect
Turn the printer on and tap the
printer name on the Bluetooth
setting screen of the iOS device.
Af ter powered on, the printer
automatically connects to the
Host that it previously connected.
How to change

printer name on the Bluetooth
setting screen of the iOS device
you want to use.
Turn the "Bluetooth" function o
on the Bluetooth setting screen
of the host that the printer is
currently connected, and then tap
the printer name on the Bluetooth
setting screen of the iOS device
you want to use.
Use case A printer is shared with the multiple
host devices.
A printer is always used with one
host device only.
The ON/OFF switching of the auto connection can be performed by operating the printer panel or using
the Star Bluetooth utility in "StarPRNT Intelligence".
For more details on the switching method, refer to "3-3. Memory Switch Setting".

WARNING
1) Do not touch the tear bar.
• There is a tear bar inside the paper outlet slot. Not only should you not put your hand in the
paper outlet slot while printing is in progress, never put your hand into the outlet even when
printing is not in progress.
• The paper cover can be opened when replacing the paper. However, since the tear bar is on the
inside of the paper cover, be careful not to place your face or hands too close to the tear bar.
2) During and immediately after printing, the area around the thermal head is very hot. Do not
touch it, as you could be burned.
