- 2. Magandang araw! Itong manuwal na ito ay kung paano gamitin ng tama ang cellphone at nandirito rin ang mga bahagi ng cellphone.
- 3. Nasa pahina 5-11 ang mga nilalaman ng manuwal na ito.
- 4. • Ito ay nag sasaad kung paano mo mapapagana ang isang gadget, at kung paano ito gamitin.Nandirito rin ang nilalaman ng cellphone para sa iyong gabay
- 6. • Battery • The battery is the only source of power supply to a mobile phone. Three types of battery are mostly used in mobile cell phones and Tablets: • Nickel – Cadmium (Ni-CD) • Nickel Metal Hydride (Ni – MH) • Lithium-Ion (Li – Ion).
- 7. • Battery Charger • Several types of Chargers are used to recharge the battery of a mobile cell phone. These include normal battery chargers, Travel Adaptor (TA), Cigar Lighter Adaptor (CLA) etc. • Switch or Key Tip • These tiny switches are used for the key pad. • Central Processing Unit (CPU) • The CPU is the Main Control Section of a mobile phone, Android Smartphone and Apple iPhone. It controls all the function and does all the processs work • RAM (Random Access Memory) • RAM is an erasable memory where older data and information can be erased and new data and information can be stored. • ROM (Read Only Memory) • A memory that can only be read. It cannot be erased. Programmable ROM (PROM) and Erasable ROM (EROM) are some other types of ROM Memory that can be erased. • Visual Display • This part of the mobile phone generates light to display all information. Display of a cell phone can be classified as follows: • LCD (Liquid Crystal Display) • VFD (Vacuum Fluorescent Display) • TFT (Thin Film Transistor Display).
- 8. • IF IC • This IC is also called Hager IC, MJOLNER IC and RF IC. It performs the function of amplification of receiving signal, mixing and demodulation. • VCO (Voltage Control Oscillator) • Controls frequency. • Audio IC • The main function of this IC is to handle and control audio frequency and produce sound. • UEM IC (Universal Energy Module) • It performs several functions like power supply, charging, audio processing, ringer, vibrator etc. • LED (Light Emitting Diode) • It is used to produce light on keyboard and display. • RF Crystal • This is the main and very important crystal in any mobile phone. Crystals of mainly 13 MHz, 26 MHz, 19.2 MHz or 36.4 MHz are used in cell phones. The phone becomes dead if this crystal is faulty.
- 9. • Ear Speaker • This Ear Speaker is mounted on the top side of the mobile phone. It helps to listen sound during incoming calls. • Microphone • It converts voice signal to electric signal or tone signal during transmission. This signal is then sent to the Audio IC. ibrator Motor • It Provides vibration alert during incoming calls or messages in silent mode or when the option is On. • External Antenna Socket • External antenna can be connected with the help of accessories in this socket. This helps to increase the range of internal antenna. • Software Connector Parts • Used for flashing of Software or Operating System. The Phone may be connected to a Computer through this connector to solve software related problems • Connector Tip • Used to interface Speaker, Ringer, Vibrator and Antenna. • USB Connector • This connector is used to download data and for charging the Phone., • Microphone • It converts voice signal to electric signal or tone signal during transmission. This signal is then sent to the Audio IC.
- 10. • Joy Stick • Used to ease the function of the user. User can control the operation of a cell phone by se Software Connector Parts • Used for flashing of Software or Operating System. The Phone may be connected to a Computer through this connector to solve software related problems • tting the functions of joystick. Hands free Connector • Helps to carry on conversation without holding the Phone in hand using Head Phone or Ear Phone. • External Antenna Socket • External antenna can be connected with the help of accessories in this socket. This helps to increase the range of internal antenna. • Memory Card • External memory storage card used to store data such as photos, videos, audio etc. SD card, Mini SD Card and Micro SD cards are used as external memory.
- 11. • SIM card Socket • Holds the SIM card and acts like a SIM reader or SIM. Memory Card • External memory storage card used to store data such as photos, videos, audio etc. SD card, Mini SD Card and Micro SD cards are used as external memory. • writer. TAHVO IC • This module also performs several important functions. OMAP Module • Performs the function of processing application software and control UI software. This is the main and very important crystal in any mobile phone. Crystals of mainly 13 MHz, 26 MHz, 19.2 MHz or 36.4 MHz are used in cell phones. The phone becomes dead if this crystal is faulty.
